LAKE DELTON, Wis. — A leading Wisconsin stem cell researcher said that major roadblocks remain before human embryonic stem cells will turn into cures for diseases.
University of Wisconsin scientist James Thomson said in a speech to the Wisconsin Newspaper Association Thursday night that transplantation therapies should work but it could take decades.
He said obstacles include learning how to turn embryonic stem cells into all types of organs and tissues in the body and then making sure cancer and other defects aren’t introduced during the transplant.
