(NASDAQ: TNGN), a leader in regenerative medicine, today announced that its Board of Directors has approved a reverse split of its common stock at a ratio of 1-for-10. The Company's common stock will begin trading on a split-adjusted basis when the NASDAQ Capital Market opens on June 14, 2012.

The reverse stock split, which was approved by Tengion stockholders, is intended to enable Tengion to regain compliance with the NASDAQ minimum bid requirement to maintain the Company's common stock listing on the NASDAQ Capital Market.
