Autologous chondrocyte transplantation is an effective treatment for articular cartilage damage but involves surgical procedures which may cause further cartilage degeneration. Human adipose-derived stem cells (hADSCs) are an alternative cell source for cartilage regeneration due to their multipotency, easy accessibility and expansion. In this study, we developed an efficient chondrogenic differentiation method and cartilage formation of hADSCs, elucidated mechanisms of enhanced chondrogenesis. Chondrogenesis was promoted in spheroids in spinner flasks. As a control, hADSCs were cultured in tissue culture dishes. Signal cascades for chondrogenesis were examined. To evaluate cartilage formation, hADSCs cultured as spheroids or in monolayer were mixed with fibrin gel and implanted subcutaneously into athymic mice for four weeks. Enhanced chondrogenic differentiation in spheroids versus monolayer culture was observed. The enhanced chondrogenesis is likely attributed to hypoxia-related cascades and enhanced cell-cell interactions. Spheroid culture in three-dimensional bioreactors is advantageous over monolayer culture for chondrogenic differentiation and subsequent cartilage formation.
