Figure 3. Effect of release or depletion of sarcoplasmic reticulum Ca²⁺ stores on the basal cytosolic [Ca²⁺] in pulmonary and renal ASMCs.

▪, pulmonary ASMCs; □, renal ASMCs. Bars indicate the change in the cytosolic [Ca²⁺] from resting levels. Error bars represent ± s.e.m. Numbers of independent experiments are shown in parentheses. Thaps, thapsigargin. * Significantly different from 10 mm CAF and 1 μM ANG II pulmonary ASMC groups (P < 0.05); † significantly different from 10 μM PE and 10 mm CAF renal ASMC groups (P < 0.05); Kruskal-Wallis one-way ANOVA on ranks and Dunn's multiple comparison procedure.
