3D printed cartilage cells successfully implanted into mice

A team of Swedish and German scientists have successfully 3D printed human cartilage cells and implanted them in mice where they proliferated and vascularized. Scientists from Chalmers University of Technology, Gothenburg University (both Sweden) and University Medical Center Ulm (Germany) have produced human cartilage cells and implanted them into young mice where, further stimulated by stem cells at 2 months, they formed vascularized tissue closely resembling human cartilage. “There is no solution for missing ears,” explained research lead professor Paul Gatenholm (Chalmers University of Technology). “You have plastic and silicone implants, which you need to put in with a titanium...
