Abstract
Dissociated capillary endothelial cells display a voltage-dependent Ca current activating around the resting potential. The initial transient component of the current corresponds to a Ca channel of the T type. Some cells also display a plateau component corresponding to a distinct dihydropyridine-sensitive Ca channel. Depolarization induced by high external K+ elicits an increase in cytoplasmic Ca concentration. Confluent cells have been found to express the same Ca permeabilities.Keywords
