Revenue arrangements with multiple components are divided into separate units of accounting if certain criteria are met,&#13;including whether the delivered component has stand-alone value to the customer. Consideration received is allocated among the&#13;separate units of accounting based on their respective selling prices.&amp;#160;&amp;#160;The selling price for each unit is based on vendor-specific&#13;objective evidence, or VSOE, if available, third party evidence if VSOE is not available, or estimated selling price if neither&#13;VSOE nor third party evidence is available.&amp;#160;&amp;#160;The applicable revenue recognition criteria are then applied to each of&#13;the units.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company recognizes revenue when&#13;the four basic criteria of revenue recognition are met: (1)&amp;#160;a contractual agreement exists; (2)&amp;#160;the transfer of technology&#13;has been completed or services have been rendered; (3)&amp;#160;the fee is fixed or determinable; and (4)&amp;#160;collectability is reasonably&#13;assured. For each source of revenue, the Company complies with the above revenue recognition criteria in the following manner:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="width: 100%; border-collapse: collapse"&gt;&#13;&lt;tr&gt;&#13;    &lt;td style="width: 5%"&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#149;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&lt;/td&gt;&#13;    &lt;td style="width: 95%; font: 10pt/115% Times New Roman, Times, Serif; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: black"&gt;Collaborative arrangements typically consist of non-refundable and/or exclusive up front technology access fees, cost reimbursements for specific research and development spending, and various milestone and future product royalty payments. If the delivered technology does not have stand-alone value, the amount of revenue allocable to the delivered technology is deferred. Non-refundable upfront fees with stand-alone value that are not dependent on future performance under these agreements are recognized as revenue when received, and are deferred if the Company has continuing performance obligations and has no objective and reliable evidence of the fair value of those obligations. The Company recognizes non-refundable upfront technology access fees under agreements in which it has a continuing performance obligation ratably, on a straight-line basis, over the period in which the Company is obligated to provide services. Cost reimbursements for research and development spending are recognized when the related costs are incurred and when collectability is reasonably assured. Payments received related to substantive, performance-based &amp;#147;at-risk&amp;#148; milestones are recognized as revenue upon achievement of the milestone event specified in the underlying contracts, which represent the culmination of the earnings process. Amounts received in advance are recorded as deferred revenue until the technology is transferred, costs are incurred, or a milestone is reached.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="width: 100%; border-collapse: collapse"&gt;&#13;&lt;tr&gt;&#13;    &lt;td style="width: 5%"&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#149;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&lt;/td&gt;&#13;    &lt;td style="width: 95%; font: 10pt/115% Times New Roman, Times, Serif; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: black"&gt;Technology license agreements typically consist of non-refundable upfront license fees, annual minimum access fees, development and/or regulatory milestone payments and/or royalty payments. Non-refundable upfront license fees and annual minimum payments received with separable stand-alone values are recognized when the technology is transferred or accessed, provided that the technology transferred or accessed is not dependent on the outcome of the continuing research and development efforts. Otherwise, revenue is recognized over the period of the Company&amp;#146;s continuing involvement, and, in the case of development and/or regulatory milestone payments, when the applicable event triggering such a payment has occurred.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr&gt;&#13;    &lt;td style="font: 10pt/115% Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="font: 10pt/115% Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr&gt;&#13;    &lt;td&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#149;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&lt;/td&gt;&#13;    &lt;td style="font: 10pt/115% Times New Roman, Times, Serif; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: black"&gt;Government grants, which support the Company&amp;#146;s research efforts on specific projects, generally provide for reimbursement of approved costs as defined in the terms of grant awards.

Internal costs include salaries and employment related expenses of the Company&amp;#146;s internal scientific&#13;personnel and direct project costs. External research and development expenses consist of sponsored stem cell research and development&#13;costs, costs associated with non-clinical and clinical drug rescue and development activities, including development of AV-101,&#13;the Company&amp;#146;s drug development candidate which has successfully completed Phase 1 development, and costs related to protection&#13;of the Company&amp;#146;s intellectual property, including, but not limited to, application and prosecution of patents related to&#13;the Company&amp;#146;s stem cell technology platform, &lt;i&gt;Human Clinical Trials in a Test Tube&lt;/i&gt;&amp;#153;, and AV-101.

Share-based compensation&#13;expense is recognized over the period during which the employee is required to perform service in exchange for the award, which&#13;generally represents the scheduled vesting period of options and warrants to purchase common stock of the Company. The Company&#13;has no awards with market or performance conditions. For share-based awards to non-employees, the Company re-measures the fair&#13;value of such awards as they vest and the resulting value is recognized as an expense during the period over which applicable services&#13;are performed by the recipient.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Income Taxes&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company accounts for income taxes&#13;using the asset and liability approach for financial reporting purposes. Deferred tax assets and liabilities are recognized for&#13;the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and&#13;liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities&#13;are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are&#13;expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in&#13;income in the period that includes the enactment date. Valuation allowances are established, when necessary, to reduce the deferred&#13;tax assets to an amount expected to be realized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Concentrations of Credit Risk&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Financial instruments, which potentially&#13;subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents.

ASU 2011-05 eliminates the option&#13;to report other comprehensive income and its components in the statement of changes in stockholders&amp;#146; equity and requires&#13;an entity to present the total of comprehensive income, the components of net income and the components of other&#13;comprehensive income either in a single continuous statement or in two separate but consecutive statements. This&#13;pronouncement became effective for fiscal years beginning after December&amp;#160;15, 2011. The Company&amp;#146;s adoption of this&#13;ASU effective April 1, 2012 did not have any impact on its consolidated results of operations or financial position; however&#13;it required modification of the format of the former &amp;#147;Consolidated Statements of Operations&amp;#148; to include total&#13;comprehensive loss and changing the title of the statements to &amp;#147;Consolidated Statements of Operations and Comprehensive&#13;Loss.&amp;#148;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In May&amp;#160;2011, the FASB issued ASU&#13;No.&amp;#160;2011-04, &lt;i&gt;Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International&#13;Financial Reporting Standards (&amp;#147;IFRS&amp;#148;).&lt;/i&gt; This pronouncement was issued to provide a consistent definition of fair&#13;value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS.

    <us-gaap:FairValueDisclosuresTextBlock contextRef="From2012-04-01to2013-03-31">&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company follows the principles of&#13;fair value accounting as they relate to its financial assets and financial liabilities. Fair value is defined as the estimated&#13;exit price received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the&#13;measurement date, rather than an entry price that represents the purchase price of an asset or liability.&amp;#160;&amp;#160;Where available,&#13;fair value is based on observable market prices or parameters, or derived from such prices or parameters.&amp;#160;&amp;#160;Where observable&#13;prices or inputs are not available, valuation models are applied.&amp;#160;&amp;#160;These valuation techniques involve some level of management&#13;estimation and judgment, the degree of which is dependent on several factors, including the instrument&amp;#146;s complexity.&amp;#160;&amp;#160;The&#13;required fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels&#13;is described as follows:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#149;&amp;#9;&lt;i&gt;Level&amp;#160;1&lt;/i&gt;&amp;#160;&amp;#151; Quoted prices&#13;(unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy&#13;gives the highest priority to Level&amp;#160;1 inputs.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#149;&amp;#9;&lt;i&gt;Level&amp;#160;2&lt;/i&gt;&amp;#160;&amp;#151; Inputs other than&#13;Level&amp;#160;1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted&#13;prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for&#13;substantially the full term of the assets or liabilities.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#149;&amp;#9;&lt;i&gt;Level&amp;#160;3&lt;/i&gt;&amp;#160;&amp;#151; Unobservable inputs&#13;(&lt;i&gt;i.e., &lt;/i&gt;inputs that reflect the reporting entity&amp;#146;s own assumptions about the assumptions that market participants would&#13;use in estimating the fair value of an asset or liability) are used when little or no market data is available. The fair value&#13;hierarchy gives the lowest priority to Level&amp;#160;3 inputs.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A financial instrument&amp;#146;s categorization&#13;within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.&amp;#160;&amp;#160;Where&#13;quoted prices are available in an active market, securities are classified as Level&amp;#160;1 of the valuation hierarchy. If quoted&#13;market prices are not available for the specific financial instrument, then the Company estimates fair value by using pricing models,&#13;quoted prices of financial instruments with similar characteristics or discounted cash flows. In certain cases where there is limited&#13;activity or less transparency around inputs to valuation, financial assets or liabilities are classified as Level&amp;#160;3 within&#13;the valuation hierarchy.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company does not use&#13;derivative instruments for hedging of market risks or for trading or speculative purposes. In conjunction with the issuance&#13;of the Senior Secured Convertible Promissory Notes and related Exchange Warrant and Investment Warrants to Platinum in&#13;October 2012, February 2013 and March 2013 (see Note&amp;#160;8, &lt;i&gt;Convertible Promissory Notes and Other Notes Payable&lt;/i&gt;),&#13;and the potential issuance of the Series A Exchange Warrant (see Note 9, &lt;i&gt;Capital Stock&lt;/i&gt;), all pursuant to the October&#13;2012 Agreement, the Company determined that the warrants included certain exercise price adjustment features requiring the&#13;warrants to be treated as liabilities, which were recorded at their estimated fair value. The Company determined the fair&#13;value of the warrant liability using a Monte Carlo simulation model with Level&amp;#160;3 inputs. Inputs used to determine fair&#13;value include the remaining contractual term of the warrants, risk-free interest rates, expected volatility of the price of&#13;the underlying common stock, and the probability of a financing transaction that would trigger a reset in the warrant&#13;exercise price, and, in the case of the Series A Exchange Warrant, the probability of Platinum&amp;#146;s exchange of the shares&#13;of Series A Preferred it holds into shares of common stock. Changes in the fair value of these warrant liabilities have been&#13;recognized as non-cash expense in other income (expense) in the Consolidated Statements of Operations and Comprehensive&#13;Loss for the year ended March 31, 2013.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&#13;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 6pt; margin-left: 0pt; text-indent: 0pt; text-align: justify"&gt;During&#13;2007 and 2008, the Company issued three convertible promissory notes with an aggregate principal balance of $4.0 million (the&#13;&amp;#147;&lt;i&gt;Original Platinum Notes&lt;/i&gt;&amp;#148;) to Platinum Long Term Growth VII, LLC (&amp;#147;&lt;i&gt;Platinum&lt;/i&gt;&amp;#148;).&amp;#160;&amp;#160;On&#13;May 5, 2011, the Original Platinum Notes were amended, restated and consolidated into a single note (the &amp;#147;&lt;i&gt;May 2011&lt;/i&gt;&#13;&lt;i&gt;Platinum Note&lt;/i&gt;&amp;#148;) with a principal balance of $4.0 million (&amp;#147;&lt;i&gt;May 2011 Amendment&lt;/i&gt;&amp;#148;).&amp;#160;&amp;#160;In&#13;conjunction with the issuance of the Original Platinum Notes, the Company determined that (i)&amp;#160;the cash payment option or&#13;put option, which provided Platinum with the right to require the Company to repay part of the debt in cash at a 25% premium,&#13;and (ii)&amp;#160;the note term extension option, which provided Platinum with the right to extend the maturity date by one year,&#13;were embedded derivatives that should be bifurcated and accounted for separately as liabilities.&amp;#160;&amp;#160;In conjunction with&#13;the issuance of the Original Platinum Notes, the Company also issued warrants to purchase 560,000&amp;#160;shares of its common stock.&#13;These warrants included certain exercise price adjustment features and, as a result, the Company determined that the warrants&#13;were liabilities, which were recorded at their estimated fair value. The Company determined the fair value of the (i)&amp;#160;put&#13;option and note term extension option using an internal valuation model with Level&amp;#160;3 inputs and (ii)&amp;#160;the warrant liability&#13;using a lattice model with Level&amp;#160;3 inputs. Inputs used to determine fair value included estimated value of the underlying&#13;common stock at the valuation measurement date, the remaining contractual term of the notes, risk-free interest rates, expected&#13;volatility of the price of the underlying common stock, and the probability of a qualified financing. Changes in the fair value&#13;of these liabilities prior to the May 2011 Amendment were recognized as a non-cash charge or income in other income (expense)&#13;in the Consolidated Statements of Operations and Comprehensive Loss for the year ended March 31, 2012.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif;

Pursuant&#13;to the Artemis Agreement, each share of common stock of Artemis was converted into the right to receive 0.9045&amp;#160;shares of VistaGen&#13;California&amp;#146;s Series&amp;#160;B-1 Preferred Stock, resulting in VistaGen California&amp;#146;s pre-Merger issuance of 1,356,750&amp;#160;shares&#13;of its Series&amp;#160;B-1 Preferred Stock. The shares of Series&amp;#160;B-1 Preferred Stock were valued, pre-Merger, at $5.545 per share,&#13;and accordingly the pre-Merger purchase price of all outstanding shares of Artemis in 2003 was $7,523,200. The total purchase price&#13;was allocated to AV-101 acquired in-process research and development and was expensed subsequent to the acquisition, since AV-101&#13;required further research and development before the Company could commence clinical trials and did not have any proven alternative&#13;future uses.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The NIH awarded the Company an aggregate&#13;of $4.2 million to support nonclinical development of AV-101 during fiscal years 2006 through 2008, culminating in the submission&#13;in November 2008 of its Investigational New Drug (&amp;#34;&lt;i&gt;IND&lt;/i&gt;&amp;#34;) application to conduct Phase 1 human clinical testing&#13;of AV-101 for neuropathic pain. In April 2009, the NIH awarded the Company an aggregate of $4.2 million grant to support the Phase&#13;1 clinical development of AV-101, and subsequently increased the grant to an aggregate of $4.6 million in July 2010.

Under the terms and conditions&#13;of the NEPA Amendment, Platinum agreed to purchase the $1.0 Million Note within five business days of the Company's notice to Platinum&#13;of the consummation of a debt or equity financing, or combination of financings, prior to February 15, 2013, resulting in gross&#13;proceeds to the Company of at least $1.0 million (the &amp;#147;&lt;i&gt;Additional Financing Requirement&lt;/i&gt;&amp;#148;).&amp;#160;&amp;#160;The Company&#13;satisfied the Additional Financing Requirement on February 12, 2013 (See Note 9, &lt;i&gt;Capital Stock&lt;/i&gt;).&amp;#160;&amp;#160;Effective February&#13;22, 2013, the Company and Platinum entered into an additional amendment to the October 2012 Agreement pursuant to which Platinum&#13;agreed to purchase an Investment Note in the face amount of $250,000 on February 22, 2013 and an additional Investment Note in&#13;the face amount of $750,000 on or before March 12, 2013, which Investment Note was issued by the Company and purchased by Platinum&#13;on March 12, 2013.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Exchange Note and each Investment&#13;Note (together, the &amp;#147;&lt;i&gt;Notes&lt;/i&gt;&amp;#148;) accrue interest at a rate of 10% per annum and, subject to certain limitations&#13;and exceptions set forth in the Notes, unless converted earlier and voluntarily by Platinum, will be due and payable in restricted&#13;shares of the Company&amp;#146;s common stock on October 11, 2015, or three years from the date of issuance, as determined by the&#13;terms of the Investment Notes. At maturity, all principal and accrued interest under the Notes shall be payable by the Company&#13;through the issuance of restricted shares of common stock to Platinum.&amp;#160;&amp;#160;Subject to certain potential adjustments set&#13;forth in the Notes, the number of restricted shares of common stock issuable as payment in full for each of the Notes at maturity&#13;will be calculated by dividing the outstanding Note balance plus accrued interest by $0.50 per share. Prior to maturity, the outstanding&#13;principal and any accrued interest on the Exchange Note and each of the Investment Notes is convertible, in whole or in part, at&#13;Platinum&amp;#146;s option into shares of the Company&amp;#146;s common stock at a conversion price of $0.50 per share, subject to certain&#13;adjustments.

As a result of these provisions, the Exchange Warrant and the Investment Warrants do not meet the&#13;criteria set forth in ASC 815,&lt;i&gt; Derivatives and Hedging&lt;/i&gt;, to be considered indexed to the Company&amp;#146;s own stock and treated&#13;as equity instruments. Consequently, the Company recorded the Exchange Warrant and each of the Investment Warrants as liabilities&#13;at their fair value, which was estimated at the issuance date using a Monte Carlo simulation model and the following assumptions:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif;

The May 2011 Platinum&#13;Note continued to bear interest at an annual rate of 10%. Platinum retained the right, in its sole discretion, to extend the maturity&#13;date of the May 2011 Platinum Note by one year to June 30, 2013.&amp;#160;&amp;#160;The May 2011 Platinum Note would have been automatically&#13;converted, subject to certain conditions, upon the last to occur of (i) the closing of an equity or equity-based financing or series&#13;of equity or equity-based financings after May 1, 2011 resulting in gross proceeds to the Company totaling at least $5.0 million,&#13;including the 2011 Private Placement (see Note 9, &lt;i&gt;Capital Stock) &lt;/i&gt;and cancellation of debt not otherwise convertible; and&#13;(ii) the Company becoming a publicly traded company (&amp;#34;&lt;i&gt;Amended Qualified Financing&lt;/i&gt;&amp;#34;).&amp;#160;&amp;#160;The number of&#13;shares issuable to Platinum upon the automatic conversion of the May 2011 Platinum Note would have been determined in accordance&#13;with one of the following three formulas, as selected by Platinum in its sole discretion: (i) the outstanding principal plus accrued&#13;but unpaid interest (&amp;#34;&lt;i&gt;Outstanding Balance&lt;/i&gt;&amp;#34;) as of the closing of the Amended Qualified Financing multiplied by&#13;1.25 and divided by $1.75 per share; (ii) the Outstanding Balance as of the closing of the Amended Qualified Financing multiplied&#13;by 1.25 and divided by the per share price of shares sold in the Amended Qualified Financing; or (iii) the Outstanding Balance&#13;as of the closing of the Amended Qualified Financing divided by the Company's per share price assuming a pre-Amended Qualified&#13;Financing valuation of the Company of $30 million on a fully-diluted basis, subject to certain exclusions.&amp;#160;&amp;#160;Under the&#13;May 2011 Platinum Note, the cash payment option previously included in the Original Platinum Notes was eliminated.

margin: 0; text-align: justify"&gt;The New M&amp;#38;F Warrant is exercisable&#13;for the number of restricted shares of the Company&amp;#146;s common stock equal to the principal and accrued interest due under the&#13;terms of Replacement Note B divided by the warrant exercise price of $1.00 per share.&amp;#160;&amp;#160;At the August 31, 2012 date of&#13;grant, the New M&amp;#38;F Warrant was exercisable to purchase 1,379,376 restricted shares of the Company&amp;#146;s common stock.&amp;#160;&amp;#160;The&#13;New M&amp;#38;F Warrant effectively permits exercise only by the cancellation in whole or in part of the Company&amp;#146;s indebtedness&#13;under either of the Replacement Notes. The New M&amp;#38;F Warrant expires on September 15, 2017. The Company determined the fair value&#13;of the New M&amp;#38;F Warrant to be $0.64 per share, or $876,800, at the date of grant using the Black Scholes Option Pricing Model&#13;and the following assumptions:&amp;#160;&amp;#160;market price per share: $0.94; exercise price per share: $1.00; risk-free interest rate:&#13;0.61%; contractual term: 5.04 years; volatility: 88.8%; expected dividend rate: 0%.&amp;#160;&amp;#160;The note discounts totaling $1,197,900,&#13;including the $199,500 remaining unamortized discount recorded prior to the modification, will be amortized to interest expense&#13;using the effective interest method over the term of the Replacement Notes. The aggregate amount of the incremental fair value&#13;of the Amended M&amp;#38;F Warrant and the fair value of the New M&amp;#38;F Warrant, $998,450, was recognized as equity and was credited&#13;to additional paid-in capital in the accompanying Consolidated Balance Sheets. The effective interest rate on the Replacement Notes&#13;at the date of issuance was 32.3%, based on the stated interest rate, the amount of discount, and the term of the Replacement Notes.&#13;Through March 31, 2013, the Company has adjusted the New M&amp;#38;F Warrant to increase the number of restricted shares available&#13;for purchase by 60,088 shares, based on interest accrued on Replacement Note B through that date. The Company has recorded the&#13;fair value of the additional shares as a charge to interest expense and a corresponding credit to additional paid-in capital.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Restructuring of Accounts Payable&#13;to Cato Research Ltd.

The principal amount of the CRL Note may, at the Company&amp;#146;s option, be automatically increased&#13;as a result of future CRO Services rendered by CRL to the Company and its affiliates from January 1, 2013 to June 30, 2013.&amp;#160;&amp;#160;The&#13;CRL Note is due and payable on March 31, 2016 and is payable solely by CRL's surrender from time to time of all or a portion of&#13;the principal and interest balance due on the CRL Note in connection with its concurrent exercise of the CRL Warrant, provided,&#13;however, that CRL will have the option to require payment of the CRL Note in cash upon the occurrence of a change in control of&#13;the Company or an event of default, and only in such circumstances.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&#13;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 6pt; margin-left: 0pt; text-indent: 0pt; text-align: justify"&gt;The&#13;Company determined that the cancellation of the accounts payable to CRL for CRO Services and the related issuance of the CRL Note&#13;should be accounted for as an extinguishment of debt.&amp;#160;&amp;#160;Accordingly, the Company recorded the CRL Note at its fair value&#13;of $857,900 based on the present value of its scheduled cash flows and assumptions regarding market interest rates for unsecured&#13;debt of similar quality. The Company determined the fair value of the CRL Warrant to be $0.48 per share, or $486,164, using the&#13;Black Scholes Option Pricing Model and the following assumptions: market price per share: $0.75; exercise price per share: $1.00;&#13;risk-free interest rate: 0.66%; contractual term: 5 years; volatility: 89.9%; expected dividend rate: 0%.&amp;#160;&amp;#160;The Company&#13;recognized the difference between the sum of the fair values of the CRL Note and the CRL Warrant less the accounts payable balance&#13;due to CRL, $335,100, as a non-cash loss on early extinguishment of debt in the accompanying Consolidated Statements of Operations&#13;and Comprehensive Income for the year ended March 31, 2013.&amp;#160;&amp;#160;The fair value of the warrant, $486,164, which is treated&#13;as an equity instrument, was credited to additional paid in capital at the issuance date. The difference between the face value&#13;of the CRL Note and its fair value, $151,100, has been treated as a discount to the note and is being amortized over the term&#13;of the note using the interest method, resulting in an effective interest rate of 12.1% on the CRL Note.&amp;#160;&amp;#160;Through March&#13;31, 2013, the Company has adjusted the CRL Warrant to increase the number of restricted shares available for purchase by 36,188&#13;shares, based on interest accrued on the CRL Note through that date. The Company has recorded the fair value of the additional&#13;shares as a charge to interest expense and a corresponding credit to additional paid-in capital.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Issuance and Restructuring of Long-Term Promissory Note&#13;to Cato Holding Company&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In April 2011, all amounts owed by the&#13;Company to Cato Holding Company (&amp;#34;&lt;i&gt;CHC&lt;/i&gt;&amp;#34;) and its affiliates, which included the $105,000 balance of an August 2010&#13;Short-Term Note issued to Cato BioVentures, were consolidated into a single note, in the principal amount of $352,273 (the &amp;#147;&lt;i&gt;2011&#13;CHC Note&lt;/i&gt;&amp;#148;).&amp;#160;&amp;#160;Concurrently, CHC released all of its security interests in certain of the Company&amp;#146;s personal&#13;property.&amp;#160;&amp;#160;The 2011 CHC note accrued interest at 7% per annum, compounded monthly.&amp;#160;&amp;#160;Under the terms of the&#13;note, the Company was to make six monthly payments of $10,000 each beginning June 1, 2011, and thereafter to make payments of $12,500&#13;monthly until the note was repaid in full.

The Company determined the fair value of the&#13;CHC Warrant to be $0.48 per share, or $120,462, using the Black Scholes Option Pricing Model and the following assumptions: market&#13;price per share: $0.75; exercise price per share: $1.50; risk-free interest rate: 0.66%; contractual term: 5 years; volatility:&#13;89.9%; expected dividend rate: 0%. The Company recognized the difference between the sum of the fair values of the 2012 CHC Note&#13;and the CHC Warrant less the carrying value of the 2011 CHC Note, $119,100, as a non-cash loss on early extinguishment of debt&#13;in the accompanying Consolidated Statements of Operations and Comprehensive Income for the year ended March 31, 2013.&amp;#160;&amp;#160;The&#13;fair value of the warrant, $120,462, which is treated as an equity instrument, was credited to additional paid in capital at the&#13;issuance date. The difference between the face value of the 2012 CHC Note and its fair value, $19,343, has been treated as a discount&#13;to the note and is being amortized over the term of the note using the interest method, resulting in an effective interest rate&#13;of 11.9% on the CHC 2012 Note.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&#13;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Restructuring of Accounts Payable to University Health&#13;Network (&amp;#147;&lt;i&gt;UHN&lt;/i&gt;&amp;#148;)&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On October 10, 2012, the Company issued&#13;to UHN: (i) an unsecured promissory note in the principal amount of $549,500, which is payable&amp;#160;solely in restricted shares&#13;of the Company&amp;#146;s common stock and which accrues interest at the rate of 7.5% per annum, as payment in full for all sponsored&#13;stem cell research and development activities by UHN and Gordon Keller, Ph.D. under the SCRA through September 30, 2012 (the &amp;#147;&lt;i&gt;UHN&#13;Note&lt;/i&gt;&amp;#148;), and (ii) a five-year warrant to purchase, at a price of $1.00 per share, 549,500 restricted shares of the Company&amp;#146;s&#13;common stock, the amount equal to the sum of the principal amount of the UHN Note, plus all accrued interest thereon, divided by&#13;$1.00 per share (the &amp;#147;&lt;i&gt;UHN Warrant&lt;/i&gt;&amp;#148;). The UHN Note is due and payable on March 31, 2016 and is payable solely&#13;by UHN's surrender from time to time of all or a portion of the principal and interest balance due on the UHN Note in connection&#13;with its concurrent exercise of the UHN Warrant, provided, however, that UHN will have the option to require payment of the UHN&#13;Note in cash upon the occurrence of a change in control of the Company or an event of default, and only in such circumstances.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company determined that the restructuring&#13;of the accounts payable to UHN under the SRCA, defined below, and the related issuance of the UHN Note should be accounted for&#13;as an extinguishment of debt.&amp;#160;&amp;#160;Accordingly, the Company recorded the UHN Note at its fair value of $467,211 based on&#13;the present value of its scheduled cash flows and assumptions regarding market interest rates for unsecured debt of similar quality.&#13;The Company determined the fair value of the UHN Warrant to be $0.48 per share, or $264,775, using the Black Scholes Option Pricing&#13;Model and the following assumptions: market price per share: $0.75; exercise price per share: $1.00; risk-free interest rate: 0.66%;&#13;contractual term: 5 years; volatility: 89.9%; expected dividend rate: 0%. The Company recognized the difference between the sum&#13;of the fair values of the UHN Note and the UHN Warrant less the accounts payable balance due to UHN, $182,500, as a non-cash loss&#13;on early extinguishment of debt in the accompanying Consolidated Statements of Operations and Comprehensive Income for the year&#13;ended March 31, 2013. The fair value of the warrant, $264,775, which is treated as an equity instrument, was credited to additional&#13;paid in capital at the issuance date. The difference between the face value of the UHN Note and its fair value has been treated&#13;as a discount to the note and is being amortized over the term of the note using the interest method, resulting in an effective&#13;interest rate of 11.3% on the UHN Note.&amp;#160;&amp;#160;Through March 31, 2013, the Company has adjusted the UHN Warrant to increase&#13;the number of restricted shares available for purchase by 19,421 shares, based on interest accrued on the UHN Note through that&#13;date. The Company has recorded the fair value of the additional shares as a charge to interest expense and a corresponding credit&#13;to additional paid-in capital.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Issuance of Long-Term Notes and Cancellation&#13;of Amounts Payable&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On February 25, 2011, the Company issued&#13;to Burr, Pilger, and Mayer, LLC (&amp;#147;&lt;i&gt;BPM&lt;/i&gt;&amp;#148;) an unsecured promissory note in the principal amount of $98,674 for&#13;amounts payable in connection with valuation services provided to the Company by BPM.&amp;#160;&amp;#160;The BPM note bears interest at&#13;the rate of 7.5% per annum and has payment terms of $1,000 per month, beginning March 1, 2011 and continuing until all principal&#13;and interest are paid in full.&amp;#160; In addition, a payment of $25,000 shall be due upon the sale of the Company or upon the Company&#13;completing a financing transaction of at least $5.0 million during any three-month period, with the payment increasing to $50,000&#13;(or the amount then owed under the note, if less) upon the Company completing a financing of over $10.0 million.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On April 29, 2011, the Company issued&#13;to Desjardins Securities, Inc.

The Company has calculated the&#13;weighted-average expected term of the options using the simplified method as prescribed by Securities and Exchange Commission Staff&#13;Accounting Bulletins No.&amp;#160;107 and No.&amp;#160;110 (&amp;#147;SAB No.&amp;#160;107 and 110&amp;#148;). The utilization of SAB No. 107 and&#13;110 was based on the lack of relevant historical data due to the Company&amp;#146;s limited historical experience as a publicly traded&#13;company as well as the lack of liquidity resulting from the limited number of freely-tradable shares of its common stock. Limited&#13;historical experience and lack of liquidity in its stock also resulted in the Company&amp;#146;s decision to utilize the historical&#13;volatilities of a peer group of public companies&amp;#146; stock over the expected term of the option in determining its expected&#13;volatility assumptions. The risk-free interest rate for periods related to the expected life of the options is based on the U.S.&amp;#160;Treasury&#13;yield curve in effect at the time of grant. The expected dividend yield is zero, as the Company has not paid any dividends and&#13;does not anticipate paying dividends in the near future. The Company calculated the forfeiture rate based on an analysis of historical&#13;data, as it reasonably approximates the currently anticipated rate of forfeitures for granted and outstanding options that have&#13;not vested.&amp;#160;&lt;/p&gt;&#13;&#13;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif;

Such cash and cash equivalents are not sufficient to enable the Company&#13;to fund its operations, including expected cash expenditures of approximately $5 million, through the next twelve months.&#13;However, in April 2013, the Company entered into a securities purchase agreement, as amended, with an institutional investor&#13;involving the Company&amp;#146;s private issuance and sale of its restricted common stock in a transaction involving a series of&#13;closings scheduled to occur between June 27, 2013 and September 30, 2013, which financing transaction is expected to generate&#13;aggregate cash proceeds to the Company of $36.0 million (see Note 16, Subsequent Events, for a further description of this&#13;private placement).&amp;#160;Additionally, the Company expects that its participation in strategic collaborations, including&#13;licensing transactions, may provide additional cash in support of its future working capital requirements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;</us-gaap:BasisOfAccountingPolicyPolicyTextBlock>

If the delivered technology does not have stand-alone value, the amount of revenue allocable to the delivered technology is deferred. Non-refundable upfront fees with stand-alone value that are not dependent on future performance under these agreements are recognized as revenue when received, and are deferred if the Company has continuing performance obligations and has no objective and reliable evidence of the fair value of those obligations. The Company recognizes non-refundable upfront technology access fees under agreements in which it has a continuing performance obligation ratably, on a straight-line basis, over the period in which the Company is obligated to provide services. Cost reimbursements for research and development spending are recognized when the related costs are incurred and when collectability is reasonably assured. Payments received related to substantive, performance-based &amp;#147;at-risk&amp;#148; milestones are recognized as revenue upon achievement of the milestone event specified in the underlying contracts, which represent the culmination of the earnings process. Amounts received in advance are recorded as deferred revenue until the technology is transferred, costs are incurred, or a milestone is reached.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&#13;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: center"&gt;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="width: 100%; border-collapse: collapse"&gt;&#13;&lt;tr&gt;&#13;    &lt;td style="width: 5%"&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#149;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;        &lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&lt;/td&gt;&#13;    &lt;td style="width: 95%; font: 10pt/115% Times New Roman, Times, Serif; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif; color: black"&gt;Technology license agreements typically consist of non-refundable upfront license fees, annual minimum access fees, development and/or regulatory milestone payments and/or royalty payments. Non-refundable upfront license fees and annual minimum payments received with separable stand-alone values are recognized when the technology is transferred or accessed, provided that the technology transferred or accessed is not dependent on the outcome of the continuing research and development efforts.

ASU 2011-05 eliminates the option to report other comprehensive&#13;income and its components in the statement of changes in stockholders&amp;#146; equity and requires an entity to present the total&#13;of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous&#13;statement or in two separate but consecutive statements. This pronouncement became effective for fiscal years beginning after December&amp;#160;15,&#13;2011. The Company&amp;#146;s adoption of this&#13;ASU effective April 1, 2012 did not have any impact on its consolidated results of operations or financial position; however&#13;it required modification of the format of the former &amp;#147;Consolidated Statements of Operations&amp;#148; to include total&#13;comprehensive loss and changing the title of the statements to &amp;#147;Consolidated Statements of Operations and Comprehensive&#13;Loss.&amp;#148;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In May&amp;#160;2011, the FASB issued ASU&#13;No.&amp;#160;2011-04, &lt;i&gt;Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International&#13;Financial Reporting Standards (&amp;#147;IFRS&amp;#148;).&lt;/i&gt; This pronouncement was issued to provide a consistent definition of fair&#13;value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. ASU 2011-04&#13;changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value&#13;measurements.
