http://dev.biologists.org/cgi/content/full/133/18/3671 Human brain tissue was extracted from living individuals undergoing surgery connected to epilepsy. Tissue slices were obtained from different areas of the brain and studied in a tissue culture system. Different assays were used to determine the presence of progenitors. And they actually managed to isolate and expand astroglial cell lines from these epileptic temporal lobe resections. These cell lines showed characteristics progenitor cells. summary As in compared to rodent brains. Interesting isn't it!
Nah...it was a joke. I purposely didn't dumb it down. The basic message is that human brains differ from rodent brains in that they have more regenerative capability. Ironically most of the research is done on mice of course. And all data is extrapolated to humans. This is done in all areas of biological research.
So brains could be a more promising source of regenerative tissue than once thought? That makes sense, if most of the study subjects thus far (mice) differ from people. What sort of unforseen consequences would there be in regrowing body parts, brain tissue and stuff? Super cancer?
