Note: The above text is excerpted from the Wikipedia article ... WebThe NIH Guidelines on Human Stem Cell Research focus on the requirements for donation of the embryo that was used for derivation. Once that determination has been made for a particular line, it applies to all subclones or modifications. For example, now that WA01 (H1) is eligible for NIH funding, WA01 lines that express GFP are also eligible.
