Study slams websites marketing stem cell therapies


In recent years, desperate patients with few options have traveled to China and other countries where doctors offer stem cell or other cell treatments for such things as spinal cord injuries, Parkinson's disease and blindness.

The new study did not assess the website claims directly by checking on how well patients actually fared at the clinics in the study.

Instead, researchers began with the 19 websites they found through Google in 2007. Treatments were promoted in several countries, including China, Mexico and Russia. None promoted treatments within the United States; one didn't give a location for treatments.
