University of Toronto researchers have developed a ” new process to treat burn victims ” : a ” portable 3D skin printer that deposits layers of skin tissue on burns and other injuries “. This process of the dimension ” a shoebox »Weighs« less than a kilo “. And could allow, ” in the future, treat the burn immediately “, By applying a” mixture of collagen (the most abundant protein in the skin) and fibrin (protein necessary for scarring of the skin) “. The study was published in IOPscience.
Axel Guenther, professor of engineering at the University of Toronto explains: ” The analogy is an adhesive tape dispenser, where instead of a roll of scotch tape, it is a kind of organic tissue that is stuck on the skin “. The advantage of this technique: to overcome the disadvantages of ” “traditional” skin grafts “Which are not always possible when” the injuries are too extensive “And who present” risk of infections “. ” Other grafting techniques are either very expensive, temporary, or take weeks to be created in the laboratory. “.
The process was tested on pigs. ” With success. “” But scientists say it will take years to test on humans. ” Indeed, ” the main problem that still arises for this 3D printer is that it must be able to resist infections “. For Doctor Palmer Q. Besseyn, general surgeon at New York-Presbyterian Hospital-Columbia and Cornell, ” Toronto research is promising in that it could potentially produce large amounts of skin transplant material in a short time “.
