Gαq/11 GPCRs drive regenerative IP -mediated IP release and Ca wave propagation
En face mesenteric artery stained with Cal520/AM (5 µM, grey) and cIP (5 μM). Ca activity was stimulated by localized photolysis of cIP (yellow circle) after a baseline recording (10 Hz). In the same preparation, the resulting Ca activity is visualized in green before (control) and in the presence of the Gαq/11 inhibitor YM254890 (1 µM, 30 mins). Scale bar: 50 μm.
