| Research Abstract |
Perinuclear mitochondria in interstitial cells may regulate endoplasmic reticulum Ca^<2+> release by buffering Ca^<2+> within microdomains between both organelles, and play a dominant role in the spatial regulation of Ca^<2+> wave generation. Pericytes in bladder suburothelium generate spontaneous Ca^<2+> transients and associatedcontractions relying on cytosolic Ca^<2+> oscillator and voltage-dependent synchrony, and thus may function as active drainage machinery of tissue metabolites.
