Calcium concentrations in retinal neuron cultures after different GluRs inhibition. (A) Calcium concentrations indicated by Fluo-4 signals. (B) Quantitative analysis of Fluo-4 signals intensity. (C) The fold change of calcium concentrations was determined by cell calcium assay commercial kit. MK, CN, and MC, which respectively block NMDAR, AMPA/KA receptor and mGluRs, were added to the cultures at a final concentration of 10, 10, and 50 μM, 30 min before 15 min glutamate insult. Experiments were repeated three times. Data were analyzed using one-way ANOVA. *p < 0.05 vs. CTL group, # p < 0.05 vs. Glu group. Scale bar = 20 μm in all panels.
