A study was carried out to examine the hypothesis that osmotic stress initiates a transient increase in the concentration of intracellular calcium ion ([Ca2+]i), and to determine the mechanisms of Ca2+ mobilization in isolated chondrocytes exposed to hypo- and hyper-osmotic stress. Osmotic stress was determined by performing tests within 12 hrs of isolation. The results indicate that both hypo- and hyper-osmotic result in significant increases and oscillations in [Ca2+]i in chondrocytes.
