Competing Interests

HTG's employer, Stanford University, has substantial interests of many kinds in human embryonic stem cell research. HTG is part of a Stanford group that stands to receive a grant from the California Institute for Regenerative Medicine (CIRM) if CIRM receives funding (see Box 1), and he is likely to apply for further grants from CIRM in the future. He is a member of the ethics committee of the International Society for Stem Cell Research. He is an unpaid member of the Ethics Advisory Committee of Affymetrix, Inc., which might have hopes of servicing a market for gene expression analysis of hESCs if they become widely used.
