About Tengion
Tengion, a clinical stage biotechnology company, has pioneered the Autologous Organ Regeneration Platform™ that catalyzes the body's innate ability to regenerate. Tengion's neo-organs and neo-tissues in development, such as bladders and vessels, combine biocompatible materials and a patient's own (autologous) cells to regenerate diseased and failing organs and tissues. Tengion's product candidates have the potential to cure - rather than treat - organ and tissue failure, enabling people to lead healthier lives without donor transplants or the side effects of related therapies.
