Abstract

This study explored the feasibility of inducing the differentiation of BMSCs into chondrocytes through co‑culture with chondrocytes in hydrogel constructs (Pluronic F‑127 gel) in vivo for the repair of goat mandibular condylar cartilage defects. Chondrocytes and BMSCs were isolated from goat auricular cartilage and bone marrow, respectively, and were mixed at a ratio of 3:7. BMSCs were labelled with green fluorescence protein (GFP) using a retrovirus vector for tracing. Mixed cells were re‑suspended in 30% Pluronic F‑127 at a concentration of 5x107 cells/ml to form a gel‑cell complex. The gel‑cell complex was implanted into the temporomandibular joint condylar articular cartilage defects. The whole temporomandibular joint and adjacent tissues were harvested at 4, 8, and 12 weeks after surgery, and gross observation, histology and collagen II expression were evaluated. In the co‑culture group, cartilage‑like tissues were formed, and abundant type II collagen could be detected by immunohistochemistry in the condylar cartilage defects. Confocal microscopy revealed that implanted GFP‑labelled BMSCs were embedded in cartilage‑like tissues. The co‑culture system described herein provides a chondrogenic microenvironment to induce the chondrogenic differentiation of BMSCs in vivo without any additional cellular factors.
