Recently, Swedish scientists successfully developed cartilage tissue by printing stem cells through a 3D bioprinter. As part of the study, a team of researchers at the Sahlgrenska Academy and the Chalmers University of Technology in Sweden harvested cartilage cells from knee surgery patients. The experts then coaxed the cells into becoming pluripotent stem cells. These stem cells were touted for their potential in developing into different types of cells. The researcher expanded and encapsulated the stem cells in a nanofibrillated cellulose. The research team then used a 3D bioprinter to print the stem cells into a structure.
