In a world first, researchers have printed multi-layered, living skin directly onto significant injuries in rats for scar-free skin repair. It's not sci-fi – they're genuinely 3D-printing skin (and possibly hair) right into damaged areas.
Full-thickness skin damage caused by traumatic injury to or extensive surgery on the face or head – to remove a cancerous tumor, say – can negatively impact a person’s confidence and self-esteem. “Reconstructive surgery to correct trauma to the face or head from injury or disease is usually imperfect, resulting in scarring or permanent hair loss,” said Ibrahim Ozbolat, the study’s corresponding author. Ozbolat and the Penn State team had previously used two different bioinks to 3D print hard and soft tissues simultaneously to repair holes in the skulls and skin of rodents.
