<<It is the first such success in the world, said Dr. Anthony Atala, the director of the institute. The research was first reported online in the British medical journal Lancet.
"These findings suggest that engineered urethras can be used successfully in patients," Atala said Monday. "This is an example of how the strategies of tissue engineering can be applied to multiple tissues and organs.">>
Atala is one of the most respected cutting edge surgeons in the world, and he speaks not only for regenerative medicine, but more specifically as Tengions chief advisor. So in a sense Tengions key technology/patents and know how is currently being used...and proven to work....being ahead of the curve is huge.
