Unproven Stem Cell Treatments Blind 3 Women (npr.org) 108
An anonymous reader quotes a report from NPR: Scientists have long hoped that stem cells might have the power to treat diseases. But it's always been clear that they could be dangerous too, especially if they're not used carefully. Now a pair of papers published Wednesday in the New England Journal of Medicine is underscoring both the promise and the peril of using stem cells for therapy. In one report, researchers document the cases of three elderly women who were blinded after getting stem cells derived from fat tissue at a for-profit clinic in Florida. The treatment was marketed as a treatment for macular degeneration, the most common cause of blindness among the elderly. Each woman got cells injected into both eyes. In a second report, a patient suffering from the same condition had a halt in the inexorable loss of vision patients usually experience, which may or may not have been related to the treatment. That patient got a different kind of stem cell derived from skin cells as part of a carefully designed Japanese study. The Japanese case marks the first time anyone has given induced pluripotent stem (iPS) cells to a patient to treat any condition. The report about the three women in their 70s and 80s who were blinded in Florida is renewing calls for the Food and Drug Administration to crack down on the hundreds of clinics that are selling unproven stem cell treatments for a wide variety of medical conditions, including arthritis, autism and stroke.

Why put MSCs in your eyes to begin with? (Score:5, Insightful)
We already know what happened here. Some people in Florida injected mesenchymal stem cells [wikipedia.org] into the eyes of three people. Mesenchymal stem cells are multipotent, but we already know that they do not form eye tissue. There was a different Japanese study that used induced pluripotent stem cells, which actually showed some promise. Those stem cells actually can become any type of tissue and are much more difficult and expensive to obtain.
So, I don't know about you, but I have a lot of questions about how injecting cells that might turn into bone, cartilage, fat or muscle into someone's eyes is supposed to help prevent blindness. And I would expect a lot of good answers and prior studies before having them do that to people.

Yeah.... Injecting ANYTHING into somebody's Eye is dangerous business.
You need more than a hunch to do that.
It's not as the article's author suggested a justification for a FDA 'Crack down' on potential stem cell treatments for things that don't
involve doing something ridiculous --- like injecting the cells directly into a vital organ such as the eyes, brain, heart, spine, kidneys, etc.

Sure, but these women had macular degeneration and were going blind anyway. MD causes the vision to deteriorate first in the center of the visual field, and then expand outward, so the most important part of sight is lost first, leaving only peripheral vision. So it's not like 3 women with perfect vision suddenly lost their sight.

They had enough vision to read and drive. There's no guarantee they would have gone completely blind, or at what rate they would have lost their vision. And they paid $5,000 for the privilege of going blind while being irresponsibly injected into both eyes instead of one. All while thinking they were taking part in legitimate research, because the "study" was advertised on a government site.
The whole thing is a horror show of profit-seeking irresponsibility.

Well when you put it like that it sounds much more reasonable, they should really be grateful for the opportunity to go blind earlier. Now they have an opportunity to pull themselves up by their own walking sticks.

By this logic, we should just let murderers go free, because the victim was suffering from a disease called Aging that was eventually going to kill them, anyways.
MD has a very gradual progression, and it is by no means certain that the person would still be alive by the time it resulted in near total blindness.

There are no good animal models for age related macular degeneration. Rodents don't get ARMD, and primates don't develop it until they are several decades old. Besides, if this treatment was put off for five years while animal trials were done, these women would be blind anyway, and their retinas would have likely deteriorated too far to recover.
