Adult stem cells?

[john leonard]

I recently got hold of the web page for Calgary, Canada, Sam Weiss, who did the research that 
found that adult mammal brains contain stem cells that can be coaxed, in vitro, to mature into 
neurons. Now, I know that at first this was done with mice, or rather rats, but didn't this 
same team make a similar discovery, about a year later, for the human brain?. The web page only 
says the embryonic human brain, but I seem to recall having seen something about the adult 
human brain as well. If you can, please inform me.
