U.S. Stem cell researchers say Bush veto has jeopardized the future of researchersmoving abroad? McCormick McCormick – a Stanford University biologist and co-author of a report in the April issue the journal Nature Biotechnology on the declining share of the embryonic stem cell research published studies by U.S. Researchers, said: It would not be surprising if we see more U.S. Human embryonic stem cell research, including some of the best researchers, moving abroad. Moreover, according to in the July in the July issue of Nature Biotechnology by Aaron Levine of Princeton University, that about 15 percent of U.S. Stem cell Principal Investigator[s] have at least get a job offer abroad, around five times.
