Business Acquisition, Pro Forma Information [Table Text Block]

The following unaudited pro forma financial information summarizes the results of operations for the periods indicated as if the purchase of Aldagen had been completed as of January 1, 2011. Pro forma information primarily reflects adjustments relating to (i) elimination of the interest on Aldagen’s promissory notes, (ii) additional stock-based compensation expense, (iii) elimination of the impact of the changes in the fair value of Aldagen’s derivative liabilities, and (iv) the amortization of intangibles acquired. The pro forma amounts do not purport to be indicative of the results that would have actually been obtained if the acquisition occurred as of January 1, 2011 or that may be obtained in the future.
