[Proliferative characteristics of the endothelial cells and pericytes from the capillary vessels of rabbit bone marrow].

The high labelling index with the low mitotic activity of pericytes as well as an interdependent change in labelling indexs and labelling intensity in endothelial cells and pericytes for 72 hours of the experiment permit pericytes to be regarded as a proliferating cell reserve for the vessels proper and, probably, for the topographically adjacent histogeneses, myeloid and osseous.
