关节软骨细胞和细胞周基质的压缩特性及其对软骨细胞代谢的影响

软骨细胞和细胞周基质(pericellular matrix, PCM)的力学特性对于关节软针的生理功能具有重要的意义。软骨细胞在压缩应力下表现出黏弹性固体材料特性，其压缩特性具有各向异性和多相性。PCM对软骨细胞具有明显的力学保护作用。压缩应力影响软骨细胞的代谢活动。软骨细胞和PCM的力学特性有许多仍未澄清，尚需进一步的研究。

Compressive Mechanical Properties of Chondrocyte and Pericellular Matrix and Its Influence on the Metabolic Activity of Chondrocyte

The normal mechanical properties of the chondrocytes and the pericellular matrix(PCM)is significant for maintaining the healthy articular cartilage. In the compressive stress environment, the chondrocytes exhibit viscoelastic solid material properties with anisotropic and inhomogeneous compressive mechanical characteristics. The PCM plays a definite mechanical protective role for the chondrocytes. The compressive stress may have an important influence on the metabolic activity of the chondrocytes. In spite of these, the biomechanical properties of the chondrocytes and the PCM are not fully understood, and still need further more study.
