More than 700 so-called stem cell clinics in the U.S. offer treatments -- often costing $5,000 to $20,000 -- experts say have no proof of safety or effectiveness, and, in many cases, no logical scientific reason to think they might work.
Hyun says it may sound harmless to move your own cells around, but not all cells are the same. “Your body’s stem cells -- they’re found, they work, and they live in a very particular system,” he says. “When you transfer them out of that system, there’s no evidence they’re going to do anything except maybe cause harm because they’re in unfamiliar territory.”
some clinics, including Berman’s, with selling drugs without appropriate approvals and with unsafe manufacturing practices.with the FDA against two clinics there. In a statement at the time, the government said: “Court decisions like this reaffirm the FDA’s compliance and enforcement efforts in the ongoing fight to protect the public from individuals and clinics who mislead patients with unapproved and potentially harmful medical products.
Stem cell clinics cloak their marketing in science, Turner and other scientists say. For example, they use proper scientific terms and fill their websites with explanations and links to scientific studies. Some clinics have patients sign waivers suggesting that their treatment is part of research. But most of these clinics have done little or no legitimate research, Turner says.
But whether such shots are useful remains an open question. “The science is still weak,” Leucht says. There has never been a large, well-designed research trial, with patients getting the treatment compared to those receiving a placebo. Before agreeing to treatments at stem cell clinics, you should ask questions about the procedure and the doctor performing it, say Emma Frow and David Brafman, both PhDs and assistant professors at Arizona State University. The pair helped co-author aon the stem cell industry, published this month, that offered details about nearly 170 stem cell businesses in the Southwestern United States.
