Immunofluorescence double-labeling of renal pelvic tissue shows ETA-R-ir on smooth muscle cells (a–c). CGRP-ir sensory nerve fibers (arrows) are found among the ETA-R-ir smooth muscle cells (d–f). In T11 DRG (g–i) and T10 DRG (j–l) ETA-R-LI was found on smooth muscle cells in vessels distributed among CGRP-ir neuronal cell bodies (arrows).
