Stem cell research in Canada: business opportunities for U.S. companies.

The ban on the use of United States (U.S.) federal funds to support new embryonic stem cell research has had a chilling effect on such research in the U.S. In Canada, significant research opportunities are available for conducting stem cell research. The opportunities include using embryos that were originally produced for reproductive purposes, and using stem cells derived from adults and animals. Stem cell research in Canada is made even more attractive in view of the availability and quality of research facilities, the lower cost of conducting research in Canada than in the U.S., and the government tax credits.
