The regulation of carbachol on spontaneous Ca2+ oscillation in cultured ICCs from the mouse urinary bladder. (A) Sequential fluorescence intensity images of Fluo-3 loaded cultured ICCs by carbachol (10-8 M). In the presence of carbachol, the [Ca2+]i oscillations were increased. (B) Sequential fluorescence intensity images of Fluo-3 loaded cultured ICCs by carbachol in the presence of atropine (10-6 M). Atropine blocked the carbachol-induced effects on [Ca2+]i oscillations. CCh, carbachol.
