Adult Stem Cell Research

Not one to ridicule other people's misfortunes, the Houston Chronicle drew a double edged sword to my moral fiber this morning. According to the article "Brains Behind New Bones" stem cells from adult bone marrow can be used to regenerate tissue for Iraq War amputees. It's an amazing feat of practical scientific reasearch because it helps soldiers regrow skin and other organs. However, part of re-building the blocks of DNA involve placing the stem cells on biodegradeable scaffolding and then stimulating them chemically, somehow. The reason that I am straining to hold my giggles is because I just caught an internet flick of a poor fellow who inexplicably had a bad run in with a tree. Can biodegradeable scaffolding also be used to mean the inside of a log cabin?
