Study Showing Results of Tengion Neo-Bladder Augment(TM) Featured in

September Issue of Regenerative Medicine

EAST NORRITON, Pa., Sept. 18 /PRNewswire/ -- Tengion Inc., a clinical stage regenerative medicine company focused on the development of neo-organs and neo-tissues, today announced that the results of a preclinical research study conducted with its Tengion Neo-Bladder Augment(TM) were published in the September issue of the Regenerative Medicine, Vol. 3, Issue 5. The paper, "Long-term durability, tissue regeneration and neo-organ growth during skeletal maturation with a Neo-Bladder Augmentation Construct" was co-authored by Tengion scientists Manuel J. Jayo, D.V.M., Ph.D., Deepak Jain, Ph.D., John W. Ludlow, Ph.D., Richard Payne, Ph.D., Belinda J. Wagner, Ph.D., and Timothy A. Bertram, D.V.M., Ph.D. along with Gordon McLorie, MD from Wake Forest University Baptist Medical Center.

The preclinical study, in which either a Neo-Bladder Augment or the subject's own native urinary bladder was surgically implanted following an 80% cystectomy and evaluated clinically at one, three, six, nine, 12, 18 and 24 months - showed that the Tengion Neo-Bladder Augment regained and maintained native bladder histology by three months. The study also demonstrated that the Neo-Bladder Augment regained baseline capacity at three to six months and baseline compliance by 12-24 months. Importantly, the Neo-Bladder Augment continued to adapt in size and function with overall animal growth, or skeletal maturation.

"The results of this study are very encouraging for our overall Neo-Bladder Augment program and, specifically, for our ongoing Neo-Bladder Augment pediatric clinical trial. The children with spina bifida in that trial are continuing to
