Muscle Mice 116

Posted by Soulskill from the hulk-squeek dept.
SilasMortimer writes "Researchers from the University of Colorado at Boulder have accomplished that for which humankind has been desperate since the dawn of civilization: turning sad, injured regular mice into angry, beefed-up super-mice. Well, okay, there's no official word in the article about the rodents' emotional states, but certainly when stem cells were injected into mice with leg injuries, the muscle grew back... almost twice as big as it was before the injury [abstract, supplemental material (PDF)]. This has many exciting implications, from better healing after injuries to slowing down the aging process to a spike in the number of cases of Generalized Anxiety Disorder among cats. I, for one, refuse to perpetuate outdated memes. (But feel free to make up for the lack.)" If these mice are bred with those given previously discovered treatments to make them smarter and fearless, we might be in trouble.

      • Technically speaking, it should be fairly easy to customize muscle clumps in humans.
        We just need a little more research in terms of how to deliberately injure muscle fibers before introducing the stem-cells.

          That's what exercise does. I damages the cells which are then repaired by the body's normal systems. I suspect stem cell treatment just speed this up.

          • The problem with this stem cell stuff, is that there needs to be enough damage to repair. Small damage from ripped muscles (through workouts) will have a small muscle increase. Big damage (perhaps surgically ripped), big increase. :)

            Of course, it would still work on lightly ripped muscles, but the dosage would have to be over a long period of time. Surgical rips would be loads quicker and a smaller window of exposure.

      The reason steroids are illegal in sports is because they are damaging to the health. People think you should be able to compete in events without doing weird, unhealthy stuff like that. A lot of performance enhancing substances are perfectly legal, and everyone does them, like powdered protein, or creatine. If you don't use protein, it's really depressing how many cans of tunafish you have to eat to make up for it. These are so unlikely to damage your health that anyone can use them without special help from a doctor, and without health problems.

      There is a scale, and of course steroids of course are on the extreme end of the spectrum, and have a lot of negative health effects. Other things, like blood doping, is mostly safe, but still carries risks and is hard to do by yourself, so it is kind of in the middle. Diet drugs are in the middle, but are legal. Protein is on the safe side. If this new technique ends up on the safe side, it will be legal. If it ends up on the unsafe side, it will be illegal. If it ends up in the middle, other random factors will end up determining what side it ends up on.

      I don't have the knowledge to comment on whether it will be easy to detect or not.
      • It's not just damaging to health. It's the cheating.

        As far as "damaging to health" goes, the dose makes the poison. There's natural variation in testosterone levels; how do you argue damaging to health, if the least-chemically-manly merely doses up to the same level as the most-chemically-manly in an event? The result is the same as a naturally-occurring level, but it was obtained by doping, therefore it's illegal.

        You could credibly argue, also, that any level of testosterone is hazardous to your l
        • Dude, your arguments seriously look like someone who has an idea and is looking for anything to support it. Don't do that. Instead look at all the evidence and try to figure out what is the most likely conclusion. Don't be like the drunk man in the saying, who used statistics for support instead of illumination.
          • Not sure what you're saying. I've never done any of that stuff, if that's what you're implying, but it's entirely possible to enhance performance with drugs in ways that are not a health risk. So, that can't be the reason it's banned. Athletes could use testosterone and EPO to bring their personal levels right up the medically defined "upper limits", therefore not a health risk, yet under current rules it would still be illegal.

            So it's about the cheating, not the health risk.

            See, for example, http: [wikipedia.org]
            • I discussed blood doping in my original post. If steroids weren't a health risk, athletes would be using them as much as they use protein now.
