Stem Cells Cure Paralyzed Rats

An anonymous reader writes "According to an article on Forbes as well as other sources, 'Scientists have used [embryonic] stem cells and a soup of nerve-friendly chemicals to not just bridge a damaged spinal cord but actually regrow the circuitry needed to move a muscle, helping partially paralyzed rats walk.'"

If only...

[Spad]

If only they put this much time and effort into finding cures for human conditions instead of wasting it all on rodents. Bloody mice get all the breaks.

Interesting that she is allowed to keep a rodent pet when she works in a laboratory, even though the rodent originally came from the lab...I work at a genetics research laboratory, and I'm not allowed to keep mice, rats, guinepigs, or hampsters as a pet at home, or keep any animal as a pet that eats any of the forementioned rodents as its normal food (cats are okay, even though they might occasionally catch mice).

The fear is that someone could introduce a parasite, virus, or bacterial infection into one of the mouse colonies, which would be devistating to our research (http://www.jax.org/research/research_areas.html), and our mouse business (http://jaxmice.jax.org/index.html). I don't handle the lab mice, or even come in close proximity of the mice on a regular basis since I'm a software engineer and this restriction still applies to me.

If the lab you work in is part of Jackson Labs, that's a reasonably paranoid restriction. If a university lab has an infection problem, they're often small enough to treat the issue medically. If not, they can buy a fresh population from, say, Jackson Labs. Jackson needs to have the equivalent of "five-nines" reliability in their animals, where a univeristy vivarium is usually happy with two or thee nines.

For those

For those rats who did not regain use of their limbs after the experiment, little miniature wheelchairs and sticks were provided.

Let's just tell the animal rights protestors that anyway.

Re:For those

[SargeantLobes]

Unfortunately, this particular lab was working with curly-wing and wingless mutants, so the freed flies took a few tottering steps, then fell out of their open tubes and collected on the floor.

Lab animals being set free often end up like that. They've been in labs for their entire lifespan (which is required, because all the variables need to be known and controllable), and they don't know how to fend for them selves. All those mice being set free usually just curl up somewhere and die. They don't really know how to look for food (they just nibble everything), and they don't know to run from predators.

Animal rights activists don't usually know anything about animals/nature. Animal rights acivists got egg collecting (from a rare species of bird, that lays it's eggs in fields) banned here last year. What they didn't know was, that when the colletors collected the first batch (which usually freezes to death) they put a flag near the nests so the farmer wouldn't drive over it. So all those years it was the egg collecting sustaining their existance (farmers don't go around putting flags near nests just for the heck of it, they've go 'better' things to do.

This is amazing

We must immediately ensure that this life-changing new medical technology is placed under a raft of arbitrary and politically motivated legal restrictions.

We must do this as quickly as possible. For science!

...literally...

[OscarBlock]

From the article ""They did something that people have been trying to do for at least 30 years and literally hit a brick wall until now," said Dr. Naomi Keitman..."

Is this why they developed an interest in repairing spinal cord injuries? I think we should be told...

Got ya

[overbaud]

"bridge a damaged spinal cord" so if anyone is thinking of sticking their head in a life sized rat trap... good news!

Reconnecting Nerves is like hand soldering

[LiquidCoooled]

a Surface mount chip.
Its always going to be messy and you will likely fuse the wrong things together.
But having some movement/sensation is good so Thumbs (and index finger) up to this research.

I think you've underestimated the level of improvement. I saw a before/after video of this on last night's network news. Before the treatment, the rat's back half was totally paralyzed. After, it was completely mobile, although it did look like one leg was a little stiff. So we're not talking about just being able to wiggle a few toes here, we're talking about getting up and walking around, albeit with a bit of a limp.

A better link for that video would be appreciated, btw - the above requires IE and MS Media Player.

Question

[Francisco_G]

Who paralyzes the rats in the first place? Do the scientists step on 'em?

soup of nerve-friendly chemicals

[losec]

thats what i'm going to call long island ice tea from now on.

Actually

[Shivetya]

getting the government out of the way has opened more doors.

many don't realize the numbers of restrictions and amounts of red tape that come with government funding. So while the motive for limiting federal participation in stem cells may be political/religous/etc in basis it does also follow the theme of letting private industry take the risks and reap the rewards.

making people well is big business but along with that comes great cost and time. Innovations come from those who are not bound by restrictions and having the government looking over one's shoulder.

look at it this way, with private entities doing the work, competeing with each other, we will may end up with different cures for the same problems allowing a broader range of people to benefit. we also have multiple avenues to not being impacted in the future by the government agencies as the work was performed in the free market.

Geeze

[TheSkepticalOptimist]

I wish I could be a rat, they can cure paralysis, aids, being overweight, being underweight, many types of cancer, mood disorders, aggression, lots of diseases and I even think baldness.

Groups like Peta think that rats are abused in laboratories, but they don't realize how easy a life they have it. Scientists are curing all sorts of problems in rats, making it easier for rats to survive. Billions of dollars are spent every year to cure rat problems.

I just wish that scientists would start curing stuff in humans, it would be nice if one of these days they started applying these discoveries on humans and maybe helping the human race out. If they could just take some of those billions spent on rat research and put it towards humans, what a wonderful world it would be.

So, hurray, scientists cure something else in some lab rat! Let me know when they start working on humans.

Unfortunately, the actual scientific possibilities were overshadowed by a bunch of political bullshit.

One could just as easily say "Ach, mein Fuerher, too bad the actual scientific possibilities of eugenics were overshadowed by a bunch of moral concerns." Part of subscribing to a moral code is realizing that its requirements are overriding. If embryos are considered human beings, which at least according to statistics of religious affiliation (add up the number of Roman Catholics, Orthodox, and non-mainline Protestants) is a belief held by the vast majority of the Western world, then one simply cannot experiment on embryos no matter how much one desires to see the results.

It seems like a lot of Slashdot posters think that the best thing human beings could do is just junk whatever moral notions they have about the dignity of the human person, and just do a lot of crazy whizbang scientific experiments just because they are there.

Here is the thing about moral codes: individuals subscribe to them according to their own beliefs. The government has no business legislating them. If christians of various flavors have a problem with stem cell research, they are free to refuse treatments based on it.

This could be crucial to the stem cell debate

[99luftballon]

If they can get a similar process in place for humans it'll cut the legs out from under the luddites opposing stem cell research (no pun intended). It's amazing how many people will decide the ethics of stem cell research aren't that much of a problem when they have the chance to see loved ones walk again, or recover from illnesses like Alzheimer's or Parkinson's.

I like this approach better: http://www.courier-journal.com/apps/pbcs.dll/artic le?AID=/20060308/NEWS01/60308003

I've met these folks. They are getting great results with procedure that is easy to duplicate AND the method uses the patient's own cells. Not only does that avoid the pesky ethics issues, there's no tissue rejection issues.
