ONLINE COVER Biomaterials to the Rescue. Damaged cartilage from years of use. A scarred heart after myocardial infarction. These types of injuries are difficult to repair because heart and cartilage tissues have a low capacity for natural regeneration. In a Perspective in this issue of Science Translational Medicine, Burdick et al. discuss the possibility of using acellular biomaterials—rather than cell-based therapies—to heal injured tissues, with a focus on heart and cartilage. The authors argue that acellular materials have matured and will continue to evolve to address clinical and regulatory challenges. [CREDIT: S. MECKELMANN/ISTOCKPHOTO]
