This invention concerns compositions of chondrocytic cells, notably human ones, and the methods for preparing and using them. More specifically, the invention describes the production of autologous human chondrocyte suspensions, employing recombinant enzymes and/or media that are compatible with pharmaceutical use. The invention also describes methods and compositions for freezing chondrocytes, notably in the absence of DMSO. The chondrocytes which are produced can be used in vivo to restore affected cartilaginous structures, such as in post-traumatic cartilaginous defects or dissecting osteochondrite of the knee or, more generally, for treating and repairing clinically significant defects in cartilage, notably in joint cartilage.
