Scientists Aim To 'Print' Human Skin 77

Posted by Soulskill from the epidermis-load-letter-what-does-that-mean dept.
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."

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.

      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.

        Yep! Until you can prove the genome of the cells used in the ink are all 100% cancer-free, count me out. However, for a burn victim whose only other treatment option is infection and a slow death, I might be willing to give it a shot.

        • Given the lousiness of conventional treatment for serious burns, and the relative ease of detecting many skin cancers, I suspect that a risk of cancer well above 0 would be acceptable(especially since ordinary human skin has that anyway). You would certainly want results markedly better than the "naive and desperate getting stem-cell shots in seedy offshore clinics" level, but even having to pick off a melanoma every few years would almost certainly be both better quality of life, and cheaper, than enduring

        Wake Forest has already demonstrated printing organs from a modified ink jet printer. I'm not sure why the article makes it sound like the idea is exclusive to other universities. Here's a short clip from NOVA on this very topic: http://www.youtube.com/watch?v=NeJPBuBEJ50

    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.

    I remember seeing a BBC (?) video somewhere about some research lab printing some human organ prototypes. The prototypes weren't functional in themselves but supposedly will be used as scaffolding for embedded heart/lung/etc sells to grow on, thus requiring the success of another technology, stem cell manipulation.
