[Research progress of different mechanical stimulation regulating chondrocytes metabolism]

As a kind of mechanical effector cells, chondrocytes can produce a variety of physical and chemical signals under the stimulation of multiaxial load in vivo, which affect their own growth, development and apoptosis. Therefore, simulating the mechanical environment in vivo has become a research hotspot in the culture of chondrocytes in vitro. Although a large number of reports have fully proved that different mechanical stimulation can regulate the metabolism of chondrocytes, the loading scheme has not been agreed. Starting from different mechanical forms, this review will explore the differences in the regulation of chondrocyte metabolism by different mechanical stimuli, so as to find an advantage scheme to promote the growth and proliferation of chondrocytes and to develop a more stable, effective and reliable experimental strategy.
