A little over a month ago, a group of Swedish researchers, including several from Sahlgrenska Academy, made big news when they not only implanted 3D printed human cartilage cells into mice, but got them to survive and grow after implantation. The cells were implanted immediately after they were 3D printed, and successfully formed their own blood vessel networks inside the mice, which is a promising step towards the eventual 3D printing and implantation of actual human organs. Now Sahlgrenska Academy is back in the news for further advances in 3D bioprinting. The team of researchers, working with Chalmers University of Technology, which also collaborated on the previous research, has successfully created cartilage tissue by 3D printing stem cells taken from the human knee.
