Inhibition of lysosomal and endosomal function enhances VSMC calcification. Confluent rat aortic VSMC were cultured in a Pi + Ca2+ (3.5 mM phosphate/3 mM calcium) calcification medium with or without indicated concentration of lysosomal inhibitor chloroquine or endosomal inhibitor dynasore for 7 days, and calcification medium was replaced every other day. (A) Effect of increasing concentrations of chloroquine on calcium deposition. (B) Effect of dynasore on calcium deposition. Top panel, Alizarin Red S staining; Bottom panel, calcium assay. The data represent 6 determinations. Values are presented as mean ± SD. *P < 0.05.
