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."

[Marxist Hacker 42]

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).

Interesting, but not quite the same thing, since you can also use adult stem cells to make GDNF. Also note it wasn't a cure- it didn't delay onset of symptoms since the surviving motor neurons also lost their connections to muscle tissue.

In addition to that, this isn't a typical stem cell therapy, where you replace damaged tissue with stem cell grown tissue of the same type. This is something altogether different- if you had a bacteria you had engineered to produce GDNF, you'd end up with EXACTLY the sam

One little difference from what you said. Embryonic stem cell research is not forbidden in the United States. The federal government just won't fund it except from a couple of pre-existing stem cell lines (which I guess are corrupted and worthless now anyway). Lot's of embryonic stem cell research happens via private funds and is often even funded through states like California.

Everything else you said is spot on.

But then of course the problem is that many of the test subjects may die before they can collect their payment. Solution: instead of buying the services of the child, simply buy the child itself outright from its parents. This would also allow the experimenters greater freedom in terms of how they treat and store their subjects, since the child would be their property and not entitled to inconveniences like "humane treatment".

Enrich third world parents, and advance first world medicine at the same time.

Re:

'But then of course the problem is that many of the test subjects may die before they can collect their payment.'

The payments go to the parents (if subject is under age) or whomever the subject chooses as next of kin (if of age). That is what would motivate desperate people to participate.

Re:Lab Rats

[milamber3]

This already happens for quite a few diseases. Look at Stem Cells Inc. and their work with Batten's Disease. These children are going to die if nothing is done so they are doing approved trial with them. The problem with using the people who are most ill is that sometimes they die before you get all the information you need from the trial. Trials are expensive and time consuming already so that's a pretty big negative to overcome.

[rucs_hack]

terminally ill who want to end their life on a meaningful note

They already do that. I had a friend who was diagnosed with a very nasty cancer that killed him in four months. Unfortunately his 'doctors' convinced him to allow them to test a drug on him. It helped him not a jot, a fact that they alluded to being likely (being of medical background I could read between the lines of what he was told), but never quite managed to explain clearly for him, and made him puke constantly. I did try to convince him to not take part, but they'd got him on the 'for the good of other people' thing. His was not the first case I encountered where this had occured, just the closest to me.

Terminally ill people make bad subjects. For one thing they're already dying, so your looking at a system in a failure condition, not much useful general data to be had there, and we are, after all, dealing with a person who may want to be doing other stuff in their last bit of time alive. They are also prone to being fragile of mind (not always, but it can happen in those who suddenly find they are dying young), so susceptible to being talked into things not in their best interests.

I'm against it, you may have gathered. Personally I think we should be growing brainless human bodies (as in never had a brain, never alive without external help), and test on them instead. Heck, we might even be able to cuts bits off them for people to use.

Well, you are against it but shouldn't the decision be left to each individual? Maybe your friend concluded that he would rather help others than do "other stuff" with his remaining time. Someone about to die would probably puke a lot anyway.

It's hardly mutilated. The body would have born acephalic. It's a question of genetics. There isn't much difference between genetically engineering a race of acephalic humans for medical purposes and aborting a fetus. A proper fetus even has a brain and the potential to be a fully functional human, the acephalic creations would never have this and would be human in name only.

Re:

It will not be acephalic. You need hypothalamus and limbic system just to allow the body to survive until it has adult-sized organs. Basic motor control is probably necessary to prevent atrophy of almost everything because of 18 years of inactivity. Once you get to this level of functioning a) you could claim that there is elementary continuousness and b) some morons will have sex with those bodies and create half-brainless children.

The first thing you learn in genetics is that it is not blended. A brainless person mated with a person with a brain will not create a person with half a brain.

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.

OK I'm confused.

[sakusha]

This makes no sense to me. I remember a long time ago (maybe 1976) when I was a pre-med student in college, I got a part time job at the hospital's Anaesthesiology Lab. Some of the doctors were always doing research on lab rats, it was my job to assist them (mostly doing computer data analysis). One day I saw a doctor doing some particularly nasty stuff to some rats, I asked him what he was doing. He said he was severing their spinal cords. I asked him why he was doing that. He told me that rats have a unique ability to partially repair their spinal cord even if it was completely severed. Then he showed me how he did it (not that I really wanted to see it). He made a little slice, a little snip, and crudely sewed the rat back up. I asked him why he didn't put some antibiotics in the wound or anything. He said, "well they're just rats." Sheesh. That was about the time I decided I didn't want to be a doctor.

So anyway, I was under the impression that rats already had the ability to repair their spinal cord even without the use of stem cells. Perhaps I've mis-remembered what the doctor/researcher said, does anyone know the details?

Re:

[Anonymous Coward]

Yes, the nervous systems of animals differ tremendously. For instance, certain types of damage on nerves in humans can render the individual immobile, but barely affect an animal.

But I guess the key-point in the summary was _helped_ to recover.

Re:

While TFA doesn't specifically give evidence for your anecdote, it does mention that "Injured rats injected with skin-derived stem cells regained mobility and had better walking co-ordination..." which seems to imply that the rats without the stem cell treatment did partially repair themselves, but the rats treated with stem cells healed better.

I thought humans could too though. I thought it was the scarring on the ends of the nerve fibres which prevented regrowth. My father severed the nerve in a finger, after several years it regrew and he could feel things again.

Scarring

[PIPBoy3000]

The other big issue is scarring. Nerves have a really hard time growing through scar tissue. What I was hoping to see in this article is how long the injuries were left untreated. If stem cells were cultivated before the injury and injected before scarring can occur, it's not going to be that helpful in real-life situations.

Re:

[TomorrowPlusX]

I have asked her -- IIRC her answer was that complete severing of the spinal cord has zero recovery.

Agreed about the mutilation bit. She opens up the spinal column, exposes the cord, and then uses a machine like a guillotine ( but with a blunt impactor rather than a blade ) to "bruise" the cord directly. Then she puts the poor rats back together and lets them heal.

She also does it at very particular locations for the purpose of watching the rat's hind legs regain control.

Re:

[sakusha]

OK thanks for the followup, that makes sense, I didn't see how complete severing could possibly heal, that's why I wondered about that incident for all these years. I guess technology marches onward, since now you have little guillotines and back then they just used a scissors. I guess they were just partially snipping at the cord with the scissors, not totally severing it.
