Ink jet skin grafts

Researchers at Wake Forest University working with the U.S. Armed forces Institute of Regenerative Medicine have invented spray-on skin. They modified ordinary ink jet printers to spray precisely calibrated layers of skin cells onto burn victims.

It's critical to cover burn wounds as quickly as possible in order to avoid infection. Currently, burns are surgically covered by skin grafts, a slow and painful process. Being able to quickly 'bandage' wounds with skin cells sprayed from a printer would be a tremendous advantage.

To use the printer, skin cells such as fibroblasts and keratinocytes are cultured and then placed in separate sterile ink jet cartridges. After a laser-generated 3D image of the wound is produced, the printer deposits the cells over the wound in a process called ‘bioprinting’.

Thus far, the system has been successfully tested on mice.

  1. A new way to treat burn victims, and even spraying skin cells--all that sounds good and normal (although we should always marvel at each new technological advance, especially in medicine), but somehow the fact that they have modified an ink jet printer makes it sound CRAZY!

  2. I know! I read as many sources as I could find about it, because I thought it might be a hoax. I did hear about it on the Skeptics' Guide though, and they usually vet their stuff pretty thoroughly.

  3. Hello, I do not agree with the previous commentator - not so simple
