Mechanical regulation of chondrogenic differentiation of bone marrow mesenchymal cells

BACKGROUND:Bone marrow mesenchymal cells are ideal seed cells for tissue engineering and cell therapy. We are seeking to improve the cartilage repair strategy based on bone marrow mesenchymal cells in vitro by use of natural mechanical transfer pathways.OBJECTIVE:To analyze the mechanical factors affecting the fate of bone marrow mesenchymal cells and utilize the mechanical strategy to induce chondrogenesis.METHODS:The first author retrieved the literature in CNKI, PubMed, Medline and Elsevier databases (1985-2015) with the key words of “mechanical regulation, bone marrow mesenchymal cells, bone marrow mesenchymal stem cells, chondrogenic differentiation, cartilage differentiation”. RESULTS AND CONCLUSION:Herein, we summarize some latest research results on the mechanical stimulus-induced chondrogenic differentiation of bone marrow mesenchymal cells, discuss the effects of different mechanical stimulations on the chondrogenic differentiation of bone marrow mesenchymal cells, as well as summarize the biological mechanism and signal pathways of the cells in response to mechanical stimulations in the process of chondrogenic differentiation. At last, this paper points out the future prospects of the key problems in this field, such as cartilage regeneration and repair strategy based on chondrogenic differentiation of bone marrow mesenchymal cells under mechanical stimulation.
