Engineers Implant Vascularized 3D Muscles 42

An anonymous reader writes "A big hurdle to creating "replacement parts" for the human body is the lack of an internal, nourishing blood system in engineered tissues. Using a stem cell "cocktail," researchers say they've now overcome that, and successfully implanted engineered muscles in lab animals. Next stop, genuine implantable pecs?"

    Well, it'll be nice to be able to graft some muscles on and all that, but I'll do what I do with software releases... I will wait until awhile after the technology is released, so that all the misfortunes occur to the impatiently eager... and then when the technology will not have a chance of leaving me a parapalegic or something, then I'll go for it...

    Now I'm even *less* motivated to exercise than before, which I thought was impossible. Maybe I could get really strong leg muscles implanted (like those of a cheetah) and then I wouldn't need to be stuck in traffic for 30-60 minutes a day. I'd just run to work at 60+ MPH!!! Abusing technology is what American's do best after all.... >_>
    • Considering the relative efficiency of cars vs humans, abusing resources is right. You will need a lot more energy from food than you car burns. That is at a normal aerobic run pace, the Cheeta can to 60 mph, but only for a short anaerobic sprint, which is an order of magnitude less efficient yet.

      Now if you were going to bike to work you might have a chance, so long as you were willing to stick to aerobic speeds. I'm not a doctor, but I suspect that to increase aerobic speeds you need to work on the c

        Humans are way more energy efficient than cars. Assuming a human could run at 60mph, and assuming gasoline could be comsumed rather than food:

        1 gallon of gasoline contains 33000 kCal (calories).
        A human burns 0.653 kCal (calories) per mile per pound of body weight.
        Assume a 200 pound man.

        200 * .653 * 60 = 7836 kCal (calories). This is about 23.75% of a gallon. About 252.68 miles/gallon.
        • Of course I'm sure the efficiecy comes from humans weighing signifcantly less than the average car.
        • Did you account for digestion inefficiencies? As your numbers for aerobic or anaerobic running?

          As you already noted, a car is significantly more mass. In fact VW's 1 liter car has similar efficiencies, despite being a car plus the man.

      Just as a fyi, if you're interested in swapping muscles with a different species, you'd probably be better off using the rat IIb fast-twitch myosin muscle filament, instead of the cheetah.

      There was a great article about gene therapy & interspecies muscle filament switching a few years ago in Scientific American, and they noted that switching muscles with another species could be problematic under duress, because the resultant strain on the quadriceps could physically rip out the hamstring, patella ten

  • If they can get nerves to grow too, then perhaps they can grow things like a tail for a person - a tail that will actually move, wiggle around, twitch, etc...

    Growing muscle tissue on demand actually means growing meat. Which can be edible meat.
