Alginate bioink suitable to bioprint iPSCs to support cartilage repair

Researchers at Chalmers University of Technology have found that iPSCs could be printed to mimic cartilage utilizing an alginate-based bioink. In a study published in Scientific Report, a team of scientists from Chalmers University of Technology and University of Gothenburg (both Sweden) have demonstrated that a nanofibrillated cellulose (NFC)-alginate composite bioink was suitable to print induced pluripotent stem cells (iPSCs) that formed cartilaginous tissue after 5 weeks. This technology has the potential to form a treatment for cartilage lesions, which can progress into secondary osteoarthritis and cause severe clinical problems. The iPSCs were coprinted with irradiated human chondrocytes and maintained...
