Emergence and distribution of intimal smooth muscle cells in the postnatal rat aorta.

Abstract excerpt

The distribution of aortic intimal smooth muscle cells in the normal rat during postnatal development was studied by electron microscopy and by staining with fluorescence-labeled phalloidin. The phenotypes of intimal and medial smooth muscle cells were almost identical at first; however, during development, the former remained synthetic, whereas the latter became contractile. Confocal laser scanning microscopy...
