Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes The Tax Reform Act of 1986 enacted a complex set of rules limiting the utilization of net operating loss carryforwards (“NOL”) to offset future taxable income following a corporate ownership change. The Company’s ability to utilize its NOL carryforwards is limited following a change in ownership in excess of fifty percentage points during any three-year period. Since the year 2000, the Company has had several changes in ownership which has resulted in a limitation on the Company’s ability to apply net operating losses to future taxable income. As of December 31, 2012, the Company has lost $26.0 million or $8.8 million in tax benefits, of net operating losses applicable to Federal income taxes which expired due to these limitations and expiration of net operating loss carryforwards. At December 31, 2012, the Company had net operating loss carryforwards of approximately $69.7 million applicable to future Federal income taxes. The tax loss carryforwards are subject to annual limitations and expire at various dates through 2030. The Company has recorded a full valuation allowance against its net deferred tax asset because it is more likely than not that such deferred tax assets will not be realized. Deferred tax liabilities were $4.1 million and $3.6 million as of September 30, 2013 and December 31, 2012, and relate to the taxable temporary differences on the goodwill recognized in the PCT acquisition in 2011, and the in-process R&D intangible asset recognized in the Amorcyte acquisition in 2011. The taxable temporary difference associated with the goodwill, which is tax deductible and will be amortized over 15 years, will continue to increase the deferred tax liability balance over the amortization period, with an associated charge to the tax provision in each period. The deferred tax liabilities will only reverse when these indefinite-lived assets are sold, impaired, or reclassified from an indefinite-lived asset to a finite-lived asset. As of September 30, 2013, management does not believe the Company has any material uncertain tax positions that would require it to measure and reflect the potential lack of sustainability of a position on audit in its financial statements. The Company will continue to evaluate its uncertain tax positions in future periods to determine if measurement and recognition in its financial statements is necessary. The Company does not believe there will be any material changes in its unrecognized tax positions over the next year.
