Scientists Aim To 'Print' Human Skin

suraj.sun sends this excerpt from CNN: "Scientists at the Wake Forest Institute for Regenerative Medicine, inspired by standard inkjet printers found in many home offices, are developing a specialized skin 'printing' system that could be used in the future to treat soldiers wounded on the battlefield. 'We started out by taking a typical desktop inkjet cartridge. Instead of ink we use cells, which are placed in the cartridge,' said Dr. Anthony Atala, director of the institute. The device could be used to rebuild damaged or burned skin. ... Burn injuries account for 5% to 20% of combat-related injuries, according to the Armed Forces Institute of Regenerative Medicine. The skin printing project is one of several projects at Wake Forest largely funded by that institute, which is a branch of the US Department of Defense. Wake Forest will receive approximately $50 million from the Defense Department over the next five years to fund projects, including the skin-creating system. Researchers developed the skin 'bio-printer' by modifying a standard store-bought printer. One modification is the addition of a three-dimensional 'elevator' that builds on damaged tissue with fresh layers of healthy skin."

    The device sells for $49.95, but if you want a refill of skin cells, that's $500. And if you buy refills from a third party, they'll charge you with a DMCA violation. It's a perfectly legitimate business model.

    We've got a better one already made. It's nothing more than a fancy airbrush and heals burn wounds MUCH faster than this device.

      I strongly suspect that the delivery mechanism is by far the most boring part of either of these systems.

      Spraying fluids and/or particle/fluid aerosols with greater or lesser precision is a basically solved problem. Yours for $50 at Best Buy or your local hobby shop. Yawn.

      Stimulating high-speed tissue regrowth, without it turning into a horrible mass of scar tissue and/or cancer, on the other hand, is the cutting edge bit. Mammalian tissue regeneration is rather more conservative than we would like, leading to permanent loss of tissue and limbs, and ugly scarring; but naive stimulation of cell growth, or introduction of pluripotent cells, has an ugly habit of reminding you why that level of conservatism turned out to be evolutionarily adaptive...

      Once you solve the hard problem of producing a safe and effective cell/drug/nutrient/whatever slurry that does what you want it to do, it likely barely matters if you use an inkjet, an airbrush, a paintbrush, or just finger-paint it on. The "ink" is the interesting bit.

    As the grafting process becomes more seamless, I wonder if it might be put to other uses, like tattoo removal. Or even applying tattoos.

    That just blew me away. Instead of weeks of painful recovery and permanent disfigurement, the burn victim is treated in about a week with little or no scarring.

    Viagra was initially researched by Pfizer as a treatment for angina, and just happened to fix erectile dysfunction *really well*. That doesn't make Pfizer sleazy, just like plastic surgeons aren't sleazy for giving a chick bigger tits if she wants them. Don't lie to yourself, you're judged on your physical appearance (or, in this case, "proportions"). Who cares if guys buying bigger dicks fund the R&D for regenerative medicine? Money is money.

    You know, the Red Cross was initially founded to help wounded troops. Now, they do disaster relief, humanitarian missions, etc. They keep thousands from dying all across the world every year. Many medical advances that we take for granted today came about through the treatment of wounded soldiers. Just because this technology is being used for soldiers does not mean it will never be developed for civilian use as well.

    From the article:

    Other universities, including Cornell University and the Medical University of South Carolina, Charleston, are working on similar projects...These university researchers say organs -- not just skin -- could be printed using similar techniques.

    So, they're working on it

    I have a couple of friends who have been the victims of some rather nasty burn injuries. They've come out of the experience healthy and dandy well down the road, but each one of them counts the experience as a life-changing event. Any technology that can help severe burn victims should be released to the civilian sector as well.

    If you bothered to use your brain for a 2#$!% minute, you would realize a few things:

    1) Soldiers are not out there because they wanted to, they decided to serve their country so you could stay home and play your video games. If they did not sign up in enough numbers, they would force you to serve as soon as they run out of volunteers. Remember every time that a soldier gets killed or looses his legs because of a bomb, that it could had been you out there had he and many others not volunteered.

    Or cause it is the only job they can get as there are not that many opportunities around. Or to pay for college. Or cause they are members of the Green Card Brigade.
    As for "your ass there instead" - there is always Canada. That is, unless your dad can arrange for you to "serve" behind a desk somewhere.
    Or to dick around in a military jet.

    2) It is good to know military budget goes into medical research that can also be used to save civilians in, say, burning buildings and not entirely to develop new guns and bombs.

    $9.7 billion budget divided over 5 million beneficiaries, 27,000 soldiers and 28,000 civilian employees, another 20,000 active-duty medical soldiers in field units, plus over 30,000 medical soldiers in the National Guard and Army Reserve.

    That is only 1.29% of the $721.3 billion DOD budget, which is again only between 49.7 and 68% of the annual US Military budget.
    So it's actually more like 0.64 - 0.87% of the total military budget, for 2011 alone.

    Just to illustrate how ridiculously little that is...
    A person making ~$50k a year, who would donate $50 each month to medical R&D - would do more for medical research funding, per dollar earned, then the entire military and defense budget of the United States of America.
    That is less than $2 a day.
