This is a very promising find for stem cell researchers. Basically, they have shown that stem cells do integrate and function within a juvenile animal brain. This is very exciting because for the first time they can actually see on a molecular level that stem cells work. Their next step is to research if this is true in adult animal brains. I'll be anticipating their results from that study. Man the science on this stuff is advancing extremely fast.
