Figure Lengend Snippet: Fig. 2. Fura-2 AM calcium imaging in mouse primary cultured urothelial cells (UCs). A: The differences in intracellular Ca2+ concentration after the application of DMSO (control); 10, 50, and 100 μM of PEA; 0.5 μM of cyclopiazonic acid (CPA); 5 μM of CID16020046 (CID); and extracellular Ca2+-free conditions in the mouse primary cultured UCs. B: Repre sentative traces of the Fura-2 ratio under each condition. Red arrows indi cate the application of each drug in B. The data are presented as means ± SE. The numbers of analyzed cells are 114, 151, 110, 121, 98, 72, 94, and 105 from the left column in A. Statistical analyses were done using Student's t-test. The level of statistical significance was set at P < 0.05. n.s., not significant, **P < 0.01.
