Creating a durable, natural-looking skin substitute to cover burn injuries or other wounds has been a bioengineer’s holy grail for decades. Now, we may be much closer, thanks to a new technique for 3-D printing skin complete with working blood vessels.
The research, done at the Rensselaer Polytechnic Institute (RPI) and Yale University, uses living human skin cells turned into a liquid “bio ink.” The bio ink is used to print artificial skin, which then grows its own blood vessel system.
