[Research and development of osteogenic differentiation of bone marrow mesenchymal stem cells].

Supercritical large area or large segmental bone defects are still a clinical problem. Researchers are committed to the development of artificial bone materials, but in order to solve the problem of poor bone formation of artificial bone materials, people are paying more and more attention to application of bone marrow mesenchymal stem cells in bone tissue engineering. In this review, bone marrow mesenchymal stem cells, osteogenic differentiation, osteoblasts cells, clinical application were used as keywords to search CNKI database, Wanfang database, Weipu database and PUBMED database by computer. The isolation and culture of bone marrow mesenchymal stem cells, bone marrow mesenchymal stem cell identification method, osteogenic induction method, osteogenic differentiation identification and clinical applicationt were comprehensively summarized in order to provide a theoretical basis for its use as a seed cell in the treatment of bone tissue diseases. Scholars have preliminarily studied the treatment of bone and cartilage defects, osteoarthritis, femoral head necrosis and other diseases with bone marrow mesenchymal stem cells combined with transplantation, and obtained good clinical efficacy.However, bone marrow mesenchymal stem cells have certain advantages and disadvantages, and further clinical studies and long-term efficacy verification are needed.
