[The cellular polymorphism of the myointimal thickening in the rabbit aorta].

Partly endothelialized myointimal thickening formed in rabbit aorta after balloon catheter injury. It was populated by cells of different shape. There were spindle-shaped cells. Y-shaped cells, cells of irregular shape with processes and stellate-shaped cells. As a rule stellate cells situated just near the endothelium. It is supposed, that the endothelium can influence the shape of myointimal cells.
