From: N-methyl-D-aspartate (NMDA) receptor expression and function is required for early chondrogenesis
Mitochondrial activity, a measure of cell viability (a) and rate of proliferation (b) on day 3 determined by MTT test and 3H-thymidine incorporation assays, respectively, in micromass cultures (n = 3 for each experimental condition) following pharmacological modulation of NMDAR function. Representative data (average ± SEM) out of 3 independent experiments showing the same tendency of changes. For each experimental group, data were normalized to that of the respective vehicle control (not shown individually). Statistically significant (*P < 0.05) differences compared to the vehicle control are marked
