Good point rocky. Because the article I read referred specifically to ACTC's hESCs in a separate section I quickly assumed that the initial reference to pluripotent stem cells was to induced pluripotent cells. But clearly that doesn't have to be the case and you are most likely correct. That would be even better as it night indicate serious interest by Pfizer in the ACTC products (and probably developments in general).......but, yikes, I hope Pfizer isn't hoping to try to reverse engineer anything! I assume Roslin and ACTC feel confident they have adequate safeguards.
