Figure 2From: The effect of oxygen tension on calcium homeostasis in bovine articular chondrocytesEffect of hypoxia and extracellular Na+ on cytoplasmic Ca2+ levels in bovine articular chondroytes. Methods as legend to Figure 1, except that during measurement of [Ca2+]I, chondrocytes were suspended in the presence (145 mM) or absence (Na+ replaced with NMDG+) of extracellular Na+. Histograms represent means ± S.E.M., n = 9. * p < 0.05 ** p < 0.02.Back to article page
