Forget stem cell tourism: Stem cell clinics in the US are plentiful

Snake Oil Salesman & Wagon
I had planned on writing about something else this week, but late last week another story caught my eye, because it served as a perfect follow-up to what I wrote about last week. To recap, I wrote about a man named Jim Gass, a former chief legal counsel for Sylvania, who had suffered a debilitating stroke in 2009 that left him without the use of his left arm, and weak left leg. He could still walk with a cane, but was understandably desperate to try anything to be able to function more normally in life. Mr. Gass was both driven enough, credulous enough, and wealthy enough to spend $300,000 pursuing stem cell tourism in China, Mexico, and Argentina over the course of four years. The result is that he now has a tumor growing in his spinal column, as reported in The New England Journal of Medicine (NEJM) and The New York Times (NYT). Genetic analysis has demonstrated that the cells in this tumor mass did not come from Jim Gass, and the mass has left him paralyzed from the neck down, except for his right arm, incontinent, and with severe chronic back pain. Worse, although radiation temporarily stopped the tumor from growing, apparently it’s growing again, and no one seems to know how to stop it. Given that the traits that make stem cells so desirable as a regenerative treatment, their plasticity and immortality (ability to divide indefinitely), are shared with cancer, scientists doing legitimate stem cell research have always tried to take precautions to stop just this sort of thing from happening in clinical trials. Clearly, “stem cell tourist” clinics, which intentionally operate in countries where the regulatory environment is—shall we say?—less than rigorous are nowhere near as cautious, as they charge tens of thousands of dollars a pop for stem cell treatments that might or might not actually have real stem cells in them.

At the time I wrote that article, I emphasized primarily clinics outside of the US, where shady operators locate in order to be able to operate largely unhindered by local governments. You’d think that such a thing couldn’t possibly be going on in the US. You’d be wrong. Last week, Paul Knoepfler, a stem cell scientist who has previously contributed to Science-Based Medicine, teamed up with Leigh Turner to publish a paper in Cell Stem Cell estimating the number of stem cell clinics in the US. The number they came up with astonished me. (more…)

Undermining the regulation of stem cell therapies in Italy: A warning for the future?

Stem cells are magical.

At least, if you listen to what docs and “practitioners” who run stem cell clinics in various parts of the world, usually where regulation is lax and money from First World clientele is much sought after, that’s what you could easily come to believe. Unfortunately, it’s not just Third World countries in which “stem cell clinics” have proliferated. For instance, they are not nearly uncommon enough in Europe. The example that is most troubling right now is Italy, and the reason is that there is currently a law being considered that would greatly weaken the regulation of stem cell therapies, so much so that on Friday I saw something that’s fairly rare: a major scientific journal published a pointed editorial about this new law. Specifically EMBO Journal published a commentary by an international group of scientists warning about the path that the government of Italy is considering entitled Regulation of stem cell therapies under attack in Europe: for whom the bell tolls.

Stem cell quackery is a very popular form of quackery these days because, well, stem cells are so magical-seeming. You can now find stem cell treatments offered for autism (one of which, offered at a clinic in Costa Rica, I’ve discussed before and involves injecting “stem cells” into the cerebrospinal fluid of autistic children for a cool $15,000). Kent Heckenlively, the man who took his daughter to the aforementioned Costa Rica clinic for this treatment, is not alone in subjecting his autistic child to such unproven uses of stem cells. Just a couple of months ago, a broadcast journalist in the Philippines named Karen Davila took her autistic son to the Villa Medica Clinic in Germany, which offers variants of stem cell therapy. One is known as “fresh cell therapy” and involves harvesting cells from lamb fetuses and injecting them into the patient. The other is called fat stem cell repair therapy, which is claimed to involve harvesting fat from the patient’s abdomen or thigh and then isolating “stem cells” from them to be injected back into the patient’s body.
