3D Printed Skin Grafts

To be able to make 3D printed skin grafts would be a complete game changer. See how living skin including blood vessels are now being 3D printed and how it will be integrated into patient’s skin.

TROY, N.Y. — Researchers at Rensselaer Polytechnic Institute have developed a way to 3D print living skin, complete with blood vessels. The advancement, published online today in Tissue Engineering Part A, is a significant step toward creating grafts that are more like the skin our bodies produce naturally.

‘Right now, whatever is available as a clinical product is more like a fancy Band-Aid,’ said Pankaj Karande, an associate professor of chemical and biological engineering and member of the Center for Biotechnology and Interdisciplinary Studies (CBIS), who led this research at Rensselaer. ‘It provides some accelerated wound healing, but eventually it just falls off; it never really integrates with the host cells.’

‘As engineers working to recreate biology, we’ve always appreciated and been aware of the fact that biology is far more complex than the simple systems we make in the lab,” Karande said. “We were pleasantly surprised to find that, once we start approaching that complexity, biology takes over and starts getting closer and closer to what exists in nature.’

Karande said more work will need to be done to address the challenges associated with burn patients, which include the loss of nerve and vascular endings. But the grafts his team has created bring researchers closer to helping people with more discrete issues, like diabetic or pressure ulcers.”
