Figure 8.
Effects of ryanodine (100 μM) on Ca2+ transients recorded in single ASMCs (ai–ii) and interstitial cells of Cajal-like cells (ICC-LCs) (bi–ii) of the renal pelvis bathed in 1 μM nifedipine. In comparison to ICC-LCs (bii), Ca2+ transients in ASMCs (aii) were only partially reduced even after 30–60 min exposure to ryanodine.
