FEATURES OF PROLIFERATIVE ACTIVITY OF BREAST CELLS IN WHITE RATS DURING PREGNANCY AND LACTATION.

Khasanov B.B. - Bukhara State Medical Institute named after Abu Ali ibn Sina

Resume

The structural and functional features of development and changes in proliferative activity of mammary gland cells of white outbred rats were studied in the dynamics of pregnancy and lactation. It was found that the most pronounced morphological changes caused by the development of the ductal and lobuloalveolar systems were detected with the onset of pregnancy, most pronounced on the 14th day of pregnancy, accompanied by a peak in the proliferative activity of both secretory and connective tissue cells of the gland. The next increase in the index of labeled nuclei of mammary gland cells was noted on the 1-3 day of lactation, probably due to an increase in the development of the glandular tree and the transfer of adoptive immunity due to the cells of the perialveolar stroma.

Key words: mammary gland, index of labeled nuclei, epithelial cells, connective tissue cells.
