    In this study, micropipette aspiration techniques were used to characterize the mechanical behavior and properties of chondrocytes and of the tissue comprising chondrons. Mechanical property measurements were made on a human chondrosarcoma cell line (KC2H3) and on primary human chondrocytes and chondrons isolated from osteoarthritic human articular cartilage. The morphology of the samples were characterized using optical and scanning electron microscopy. Results suggest that chondrocytes, chondrosarcoma cells, and the chondrocyte pericellular matrix behave as viscoelastic solids. This in turn indicate that the micropipette aspiration technique can provide a sensitive means of determining changes in cellular mechanics and local tissue properties at a microscopic scale.
