Liquid hydrogels and BMSCs were co-cultured in vitro with the addition of Factor A and Factor B, and the hydrogel mixture was cured with UV light irradiation. The cured hydrogel mixture was designed as a bone defect and cartilage defect, and it was used to fill the osteochondral defect area in layers. Factor A can promote the differentiation of BMSCs into chondrocytes and promote chondrogenesis. Factor B can induce the differentiation of BMSCs into osteoblasts and promote regeneration.
