Video: Researchers Can 3D Print Living Skin With Blood Vessels Included

Researchers from Rensselaer Polytechnic Institute have succeeded in developing a way to 3D print living skin, complete with blood vessels.

According to the university’s official website, the result of the research, which has been published in Tissue Engineering Part A, demonstrates significant step toward creating grafts that are more like the skin our bodies produce naturally.

In this paper, the researchers show that if they add key elements — including human endothelial cells, which line the inside of blood vessels, and human pericyte cells, which wrap around the endothelial cells — with animal collagen and other structural cells typically found in a skin graft, the cells start communicating and forming a biologically relevant vascular structure within the span of a few weeks.

“This significant development highlights the vast potential of 3D bioprinting in precision medicine, where solutions can be tailored to specific situations and eventually to individuals,” said Deepak Vashishth, the director CBIS.

“For those patients, these would be perfect, because ulcers usually appear at distinct locations on the body and can be addressed with smaller pieces of skin,” Karande said. “Wound healing typically takes longer in diabetic patients, and this could also help to accelerate that process.”
