Nanofiber spheres carry healing cells into cartilage wounds

Nanofiber spheres carry healing cells into cartilage wounds: "Cartilage wounds can be very difficult to treat. While they may eventually heal on their own, the resulting tissue often won't take the same form – or allow for the same function – as the original. Cartilage injuries are often treated with a process known as ACI (autologous chondrocyte implantation), in which a patient's own cells are injected at the wound site to form new tissue."
