Comment Transplant rejection (Score 1) 201
I'm still waiting for the results of the two brothers who reported that they could build new hearts, kidneys, etc. by growing cells on a soluble matrix the shape amd size of the organ needed by using "directed" stem cells! Now that would completely avoid transplant rejection,without drugs or cell manipulation affecting the recipient's imune system. This was in SCientific American a few years back. Still working on it, I guess?
