He was sure the dogs immune system would reject the cat gut, but once again the transplant was successful.

Badylak did not expect Rocky to survive the night, but he figured that if the animal had not bled out by morning, it would prove the intestine was sturdy enough to pass blood and hence worthy of further study. "Because of complications of that severe break there was a lot of internal bleeding inside these muscle compartments and that caused swelling," Clark told CBS News. Last February he and collaborators announced that they had, regenerated one of the bodys most scar-prone tissues, the inner lining of the esophagus, in five cancer patients.
