  • Scientists discover cell that could help people regrow limbs

    http://www.theverge.com/2013/5/23/43...b-regeneration

    Researchers have identified a cell that aids limb regrowth in Salamanders. Macrophages are a type of repairing cell that devour dead cells and pathogens, and trigger other immune cells to respond to pathogens. In humans, they're also important to muscle repair, which led Dr. James Godwin, of the Australian Regenerative Medicine Institute (ARMI) at Monash University, to research whether the macrophages found inside Salamanders are related to the animal's ability to regenerate limbs.

    THE CELLS COULD RELEASE CHEMICALS TO TRIGGER REGENERATION

    Salamanders are unique in the vertebrate world as they're capable of repairing their hearts, tails, spinal cords, brain, and regrowing limbs. This makes them an obvious candidate for regenerative research. Godwin and the team at ARMI removed the macrophages the Salamanders and found that the animals were no longer able to regenerate limbs. He believes that the cells release chemicals that are vital to the Salamanders' regenerative powers. More research is needed to establish exactly how regeneration works, and Godwin is currently conducting experiments to investigate. "This really gives us somewhere to look for what might be secreted into the wound environment that allows for regeneration," he tells ABC News.

    Although understanding the Salamander's abilities may one day lead to impossible-sounding feats like limb regeneration in humans, there are more-immediate benefits that could come from the research. Less ambitious goals such as scarless healing, could be attainable. "The long-term plan is that we'll know exactly what cocktail to add to a wound site to allow salamander-like regeneration under hospital conditions."
    Gotta be careful though, don't want to end up like this guy

    That's really interesting but you have to wonder what happens to all these studys. For instance remember the Larva worm back in 98 where they had retracted cells and injected them into mice which increased the mice original life span by six months?

    Again this was way back in 98 so who knows what happened with that, guess it just didn't work out the way they had hoped. But anyway I think if a lot of these scientist could get past the whole patton idea and share their reseach and studies we'd be a lot futher along in a medical science than we are today.

      Everyone can take a lesson from Jonas Salk. The advancements of science and healthcare should be for the good of everyone, not for one's pockets and not for the rich. That's just my opinion.

        It's nice that they found this but seeing as how good it can be for humanity the FDA won't approve any treatments using this technology until 2050.

          That's really interesting... I'd like to see that happen, but like Houshmazode says, probably not for a while.

            There's a massive amount of steps to go from identifying some mactophages to a workable human treatment.

            Stem cells are probably much closer to regrowing body parts than these will be for a long time.
