4. When does NIH anticipate that more stem cell lines will become available?
As of September 1, 2003, there are 12 human embryonic stem cell lines that federally supported researchers may purchase. This number is up from only one or two lines in Spring 2002. The increased availability of the lines is a direct consequence of NIH’s funding of infrastructure awards to support cell providers to develop their eligible lines into distribution-quality, well-characterized cell lines. Up-to-date information on available lines can be found on the NIH Stem Cell Registry.
