Lord Patel of Dunkeld, the chairman of the UK National Stem Cell Network and a chancellor at Dundee University, says embryonic stem cell research is simply not working.
He conceded in an interview with the Scotsman newspaper that the controversial science may never deliver new treatments for diseases.
"In terms of embryonic stem cell therapy, there is currently no such therapy that is available in a large number of patients," he said.
Patel also admitted scientists may never be able to overcome the hurdles -- such as the development of tumors or immune syndrome rejection issues -- that plague embryonic stem cell research and make it risky in humans.
Haven't we been saying this all along? Do these "scientists" think they will get away with research for much longer, when it's clear adult stem cells have been a proven success?
