Abstract

Osteoarthritis (OA) is a chronic disease in elders and athletes due to limited regenerative capacities of cartilage tissues and subsequently insufficient recovery of damaged sites. Recent clinical treatments for OA have utilized progenitor cell-based therapies for cartilage tissue regeneration. Administration of a single type of cell population such as stem cells or chondrocytes does not guarantee a full recovery of cartilage defects. Therefore, current tissue engineering approaches using co-culture techniques have been developed to mimic complex and dynamic cellular interactions in native cartilage tissues and facilitate changes in cellular phenotypes into chondrogenesis. Therefore, this paper introduces recently developed co-culture systems using two major cell populations, mesenchymal stem cells (MSCs) and chondrocytes. Specifically, a series of examples to describe (1) synergistic in vitro activations of MSCs by paracrine signaling molecules from adult chondrocytes in co-culture systems and (2) functional in vivo tissue regeneration via co-administration of both cell types were reviewed. Based on these findings, it could be speculated that engineered co-culture systems using MSC/ chondrocyte is a promising and feasible cell-based OA therapy in clinical aspects.
