Inkjet-like device 'prints' cells right over burns

REUTERS/Wake Forest Institute of Regenerative Medicine/Handout Inspired by a standard office inkjet printer, U.S. researchers have rigged up a device that can spray skin cells directly onto burn victims, quickly protecting and healing their wounds as an alternative to skin grafts.
They have mounted the device, which has so far only been tested on mice, in a frame that can be wheeled over a patient in a hospital bed, they reported on Wednesday.
A laser can take a reading of the wound's size and shape so that a layer of healing skin cells can be precisely applied, said the team at Wake Forest University in Winston-Salem, North Carolina.
"We literally print the cells directly onto the wound," said student Kyle Binder, who helped design the device. "We can put specific cells where they need to go."
