Your Old Inkjet Printer Could Aid Burn Victims

Looking for a place to toss your old inkjet printers? A team of scientists working to create human tissue may have a good use for them. Inkjets that are ten years old, they say, are perfectly suited to create sheets of human skin and other tissue that one day may help burn victims and even manufacture organs.
Vladimir Mironov, director of the Shared Tissue Engineering Laboratory at the Medical University of South Carolina, is one of the scientists who has rigged Hewlett-Packard and Canon inkjet printers to shoot out proteins instead of ink, and to capture tissue on specialized gel instead of paper. Older printers work well because their spray nozzles have larger holes and are less likely to damage fragile cells. It would be great to have a use for these old printers instead of searching for a place to recycle them safely.
The "skin printing" research, although in early stages, aims to replace the current skin-graft method, which can lead to postoperative complications, says Anthony Atala, a researcher at Wake Forest University School of Medicine. Today, burn victims receive skin grafts from unburned parts of their body or from skin tissue artificially grown in a lab. But trouble can arise, particularly when the body rejects grafts that don't exactly replicate human tissue. Also, grafted skin can tighten over time, causing discomfort and itching. Skin made from inkjet printers may come closer to replicating human tissue, Atala says, because it is created using skin-tissue cells. While skin printing begins with the same process of cultivating cells used in skin grafting, Atala says that the printers create skin more efficiently. "We're seeing a better-quality skin that will cover more area," he says. "The quality of the tissue is higher."
How Idea Came Up
Thomas Boland, an assistant bioengineering professor at Clemson University and another researcher involved in the project, says he came up with the idea one day when overseeing students who had become frustrated with earlier research trying to "stamp" skin cells. "I went to the lab to look around and saw an unused inkjet printer sitting there in the lab. I thought, 'Why not use that?'"
Atala and Boland say the technology could be used clinically in a few years for burn injuries, accidents, and extra skin coverage. After that, the researchers hope they can create other types of organs and even body parts using inkjet printers. If they are successful, the possibilities are nearly limitless: Printed organs could be created for use in transplants and for drug testing; and the technique could even allow plastic surgeons to reproduce Nicole Kidman's nose, for example (if she were to donate her cells).
Sound futuristic? Those types of cosmetic and transplant applications probably are, says Atala. "As you get into more complex tissues, you need more ingredients, and we're still working on that."
I'm sure by next week they will be sending out spam that claims they can create "male enhancements" from these inkjet printers.
well my wife says i make love like a tractor
feed printer
I'm totally ga-ga at this creation. Amazing.
Amazing what those "dumb, uneducated Red Staters" can come up with! Next thing you know, they may be using that old washing machine ("that 'un that narly kilt 'Ole Blue' and a coupla' other hounds when the front porch fell in last summer") as a centrifuge to enrich U-235.
That way they get fuel for their nukular still out back ("Man, talk about a KICK from that 'Branch water' -for medicinal purposes only, of course") and they get a supply of depleted uranium for casting long range bullets for their Barrett .50 cal 'varmit gun'.
No wonder internet porn is so popular.
Drug testing?
My guess is that if they could manufacture a liver, kidney, etc. they could test for drug toxicity and effectiveness w/o having to make use of humans for drug trials.
Drug trials are done in three phases: Phase I studies are usually just a test to see what a "safe" dosage of that particular drug is. It's a limited pool of patients, and they're not given any hope that the drug may cure them.
LoL. you're probably right
LOL!
Sheesh, like cartridges aren't way expensive already.
This sounds like true ingenuity at work.
Could Dot Matrix printer be used? :)
Could be the PTO.
Looking for a place to toss your old inkjet printers?
...and we all are thinking...YES! Where do we send them? Then we read the entire article and find there is no address or contact info.
Turns out there was a key word that dashes all hope of finding a good place for the dozens of old ink jet printers my school district sends to the landfill each year.
A team of scientists working to create human tissue may have a good use for them.
Key word "may". As in, maybe someday, but not today.
Got your attention though............
power take off?
Yes. An attempt at humor.
This new skin is wonderful. I haven't looked it up to see if this is the same thing but my daughter received Transcyte grafts when she suffered 2nd and 3rd degree burns from her chin down. She healed faster than she would have with traditional grafts and has very minimal scarring.
