Scientists Create 3D-Bioprinted Hair Follicles In Lab-Grown Skin

New research has seen scientists use 3D bioprinting to sprout hair follicle-like structures into lab-grown human skin tissue. Researchers at the Rensselaer Polytechnic Institute in the US start the process by “growing “ samples of skin and follicle cells in a lab, after which they’re mixed with special proteins and other materials to create a so-called “bio-ink”. This substance is then inserted into lab-grown skin using an extremely thin needle that builds up the structure layer by layer, just like …
