The pharmacological properties of voltage sensitive calcium channels (VSCC) were examined in a rat aortic smooth muscle cell line (A10). The inorganic VSCC blockers Co2+ and Cd2+ blocked 45Ca2+ uptake into these cells in both 5 mM K+ and 50 mM K+ (depolarizing) conditions. The organic VSCC antagonists nitrendipine, nimodipine, D-600 and diltiazem also blocked 45Ca2+ uptake at low concentrations. The relative potencies of blockade were similar to those found in intact vascular smooth muscle. The VSCC "agonist" BAY K8644 enhanced 45Ca2+ uptake and this effect could be reversed by nitrendipine. These results indicate that A10 cells possess VSCC and that these VSCC behave similarly to those in authentic smooth muscle.
