Skin Stem Cells Used to Mend Spines of Rats

The Toronto Star reports researchers have used adult skin stem cells to heal spinal cord injuries in rats. "Injured rats injected with skin-derived stem cells regained mobility and had better walking co-ordination, according to the study published yesterday in the Journal of Neuroscience. The skin-derived stem cells, injected directly into the injured rats' spinal cords, were able to survive in their new location and set off a flurry of activity, helping to heal the cavity in the cord."

It has never been a better time to be a rat. no cancer or diabetes and now no paralasys.

Except for the part where they first give you cancer, diabetes, and paralysis.

If humans were rats we would have cured all major illnesses by now.

Yes, but you would be a tiny part of a semi-formal, well-established, institutionalized breeding program. Your relatives would be your parents, siblings and cousins all at the same time due to inbreeding. You and your fellow rats would have been carefully designed genetically to custom physiological specifications so as to make experimenting easy and meaningful. Like for example, you would have no immune system so that foreign cells can be incubated inside your body without suffering tissue rejection issues. Or you would be genetically predisposed to some congenital disease so that drugs can be tested on you for effectiveness.

I say all this in jest, of course. It is important to realize that success with rats are accomplished only with the benefit of an incredible ammount of control excercised by researchers that translate very poorly to the realistic world human beings are living in. Beyond these initial animal trials, there are still an incredible number of hoops that medical researchers have to jump through before they can come up with something that is injectable into you.

Federal funding of adult stem cell research already exists. It's the embryonic stem cell research that is forbidden in the United States; and despite being legal in other countries, has yet to achieve even ONE useful cure. Where Adult Stem Cells, like in TFA, are now up to 20 or 30 miracle cures of a variety of injuries from heart attacks to severed spine paralysis. One ASC researcher has even claimed that he can regenerate 30,000 human brains from a single Grey matter stem cell (though, one would suspect that any knowledge the donor had would not be so duplicated- after all growing nervous tissue does not create the connections between those nerves).
