Abstract
Membrane potential has been recorded from endothelial
cells of the rat inferior vena cava. The resting membrane potential of venous endothelial cells was 69±4
mV, which was about 20 mV more negative than resting
potential of rat arterial endothelial cells measured
under the same experimental conditions. 40% of the
vein studied demonstrated spontaneous oscillations
of endothelial membrane potential. These oscillations
were found to be Ca 2+ action potentials generated in
the vein smooth muscle and electrotonically transferred
into the endothelial cells.
Keywords:
ENDOTHELIAL CELLS, Membrane potential
