Bogus Stem Cell Therapies Sold on Internet

WEDNESDAY, Dec. 3 (HealthDay News) -- Expensive, sham stem cell therapies are being hawked directly to desperate patients over the Internet, experts say.

In response, the leading organization of stem cell scientists on Wednesday issued guidelines to steer research in the field toward responsible, practical uses.

"Stem cell research is progressing so rapidly and has sparked a lot of interest in translational research [including] among patients in hopes for therapies," said Insoo Hyun, lead author of the paper outlining the guidelines and an associate professor of bioethics at Case Western Reserve University School of Medicine in Cleveland.

"At the same time," he said, "legitimate science is speeding ahead and getting to the point where there needed to be more of a road map to take the basic knowledge to clinical applications."

Although Hyun had not heard of patients actually been harmed by so-called stem cell therapies, he said he feared that "it's only a matter of time."

The new guidelines were published in the December issue of Cell Stem Cell.

Experts hailed the move.

"We clearly need guidelines for around the world to make sure that appropriate research is done before clinical work is undertaken in patients," said Paul Sanberg, distinguished professor of neurosurgery and director of the University of South Florida Center for Aging and Brain Repair in Tampa. "We see desperate patients all the time and want to make sure that any therapies they take come from responsible research groups."

"There is tremendous confusion about the two types of stem cells -- embryonic stem cells and adult progenitor stem cells. The difference is monumental, and needs to be clarified," said Dr. Darwin J. Prockop, director of the Texas A&M Health Science Center College of Medicine Institute for Regenerative Medicine at Scott & White, who also holds the Stearman Chair in Genomic Medicine at the center.

In an accompanying commentary, Canadian researchers analyzed 19 Web sites unearthed by a regular Google search, all of which peddled expensive stem cell therapies for everything from stroke to allergies.

Different clinics in China (Beike Biotech), the Ukraine (ACT) and elsewhere claim to have treated thousands of patients for neurological disorders including multiple sclerosis, Parkinson's disease, spinal cord injury and Alzheimer's disease, congenital conditions such as autism and cerebral palsy, as well as allergies, heart conditions and even cosmetic procedures. However, the University of Alberta team was unable to find any studies that had even investigated stem cell therapy for Parkinson's disease or for Alzheimer's, for example.

Nowhere, apparently, was there any authentication of whether the stem cells actually were stem cells, or where they had come from.

Stem cells most often, but not always, came from the patient's own bone marrow. Others reportedly came from aborted fetuses, animal tissues or donor tissues.

Web site information tended to be heavily skewed toward the alleged benefits of the process, and away from its risks. And the price? According to the paper, when advertised, the average cost of these therapies -- excluding airfare and accommodation -- was $21,500.
