Lack of population diversity in commonly used human embryonic stem-cell lines
We determined the genetic ancestry of a large collection of stem-cell lines. We have found that widely distributed stem-cell lines lack population diversity and that none of these lines derive from populations with recent African ancestry. Efforts to derive and disseminate new stem-cell lines should now emphasize underrepresented poplulations, to allow researchers to assess the extent to which the ancestry of stem -cell lines influences disease models, cellular therapies, and drug screeening with the use of stem cells.
