3D printing creates "living skin" with blood vessels

Researcher Pankay Callander said: "Any clinical treatment at the moment is more like a 'glamorous' creation that accelerates wound healing but eventually falls off and cannot be combined with host cells."the current lack of a functioning vascular system in skin transplants, Callander has been working on this challenge technique for many yearsThe team found that once 3D-printed skin was transplanted into the experimental mice' bodies, the blood vessels on the 3D-printed skin began to connect to the mice's own blood vessels"It's very important, which means that there's actually blood and nutrients transferred to the graft and it's going to keep the graft alive,"Callander saidTo bring 3D-printed skin technology to clinical levels, researchers need to use a similar CRISPR technology to edit donor cells so that the patient's body can receive skin transplants, which we haven't yet achieved yet, but we're one step closer to the goal"
