[Features of the reproduction of epiphyseal cartilage perivascular cells according to the results of an autoradiographic study].

In the system of a vascular-cellular complex of cartilage epiphyses the perivascular cells exhibited the highest proliferative activity, as revealed by autoradiography with labelled DNA precursor (3H-thymidine). The constant loss of cells after division in this population is probably associated with their differentiation and transition into another state. This phenomenon is strongly pronounced at the centre of enhondral ossification, and perivascular cells could be considered as one of possible sources of histogenesis developed in cartilage epiphyses.
