Structure of the placental arterial bed was studied using histological and morphometric methods. The formation of smooth muscle regulatory complexes in blood vessels of the chorionic plate and chorionic villi was demonstrated. These complexes are genetically determined and represent a variant of compensatory and adaptive reorganization of the placental(More)
Smooth muscle cells from the arterial wall of placental chorion were studied at 39-40-week gestation. The content of mono- and binuclear tetraploid myocytes was higher in sites of arterial branching and turns (27.3% vs. 4.4% straight parts of the arteries; DNA cytophotometry data). Mitoses were found only in these arterial regions (0.18%). Regional changes(More)
