3D-Printed Skin Promises Scar-Free Healing and Hair Growth

Penn State researchers develop groundbreaking bioprinting technology for reconstructive surgery.

Researchers have successfully 3D-printed multi-layered, living skin directly onto wounds in rats, potentially revolutionizing scar-free skin repair.
The technology, developed by Penn State researchers, also shows promise for hair growth, aiming for more natural-looking reconstructive surgeries.
The bioprinting process involves using a mixture of fat-derived stem cells, extracellular matrix, and a clotting solution, enabling the formation of full-thickness skin.
Within two weeks of application, the bioprinted skin facilitated near-complete wound healing and initiated early stages of hair follicle development.
This advancement could significantly impact dermatology, hair transplants, and plastic and reconstructive surgeries by providing more aesthetically pleasing outcomes.
