magtv, I agree, it appears that Pfizer is looking at the Roslin pluripotent stem cells but not currrently looking at the ACTC hESCs. However, they may well be hoping to work their way over to the ACTC cells.

magtv and elk,

I believe all Roslin cells developed to date are hESC's?

Secondly, they are pluripotent as will be the single blastomere lines developed through ACT. If the single blastomere lines NED 1-4 were not pluripotent why would the NIH be trying to include them in this definition?

Therefore, the NIH proposes replacing the current definition of hESCs in
Section II with the following: ‘‘For the purpose of these Guidelines, ‘human embryonic stem cells (hESCs)’ are pluripotent cells that are derived from early stage human embryos, up to and including the blastocyst stage, are capable of dividing without differentiating for a prolonged period in culture, and are known to develop into cells and tissues of the three primary germ layers.’’
