Endothelial and smooth muscle cell conduction in arterioles controlling blood flow.


We performed intracellular recording with Lucifer yellow dye microinjection to investigate the cellular pathway(s) by which constriction and dilation are conducted along the wall of arterioles (diameter 47 +/- 1 microns, n = 63) supplying blood flow to the cheek pouch of anesthetized hamsters. At rest, membrane potential (Em) of endothelial (-36 +/- 1 mV… (More)
