According to LifeNews:
The Ion Channel Media Group, a private biotechnology and advertising firm, has released a list of the top stem cell research laboratories in the world.
The ranking was compiled using the publication and citation history of nearly 5000 stem cell research labs.
The survey found that most of the laboratories in the top 25 are from the United States, despite President Bush’s limits on using taxpayer funds to pay for any new embryonic stem cell research.
All of the top eight stem cell research labs hail from the U.S., including the number one center, Irving Weissman’s lab at Stanford. Catherine Verfaillie’s laboratory at the University of Minnesota earned the number two spot based upon her work with adult stem cells derived from bone marrow.
