in this report we describe that in primary cultures the mean surface density of pinocytotic vesicles , evaluated by computerized morphometric analysis of endothelial cell plasma-membrane , dramatically decreases with respect to that of the cells immediately detached from the arterial wall ( 6.7 +/- 1.1 microns2 against 19.5 +/- 2.2 microns2 , p less than 0.001 ) .
