Printing Living Skin into Wounds for Scar-Free Surgery
May 7, 2024 | Terry Sharrer
“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. In the current study, they went a step further. They started with fat (adipose) tissue from patients undergoing surgery, extracting the network of molecules and proteins – the extracellular matrix – that provide the tissue with structure and stability. This formed one component of the bioink. The second component was stem cells taken from the fat tissue. The third was a clotting solution containing fibrinogen, to help the other components bind to the injury site. Each component was loaded into separate compartments in the bioprinter.” MORE
