Matrix-assisted autologous chondrocyte transplantation (MACT) is a promising method for regeneration of articular cartilage in the knee joint. To optimize a standardized application of MACT, the effect of cell culture parameters passage, cell yield and membrane-holding time on in vivo-regeneration of cartilage defects after MACT in a rabbit model was analyzed. Results of this study display that changing culture parameters lead to significantly different gene expression profiles in vitro and in vivo. For the first time, their combinative effects were analyzed showing important interactions. Clinical MACT may benefit from optimal orchestration of the cell culture parameters passage, yield and time.
