The regularities of correlation of process of endometrial cells proliferation and death during the implantation of embryo into front and back walls of uterus

Abstract

The decidual tissue performs numerous functions during pregnancy to provide for the progress of pregnancy and embryo development. These numerous functions initiate the participation of several cell types in the realization of decidual functioning. Decidual cells replace uterine epithelium and form a new cell barrier between the mother and the fetus. Proliferation activity of endometrial cells of front and back walls of uterus is changing different types during the implantation. The implantation of embryo into a back wall of uterus is a signal for increasing of proliferation activity of endometrial cells into the front wall of uterus.

Unlike from this, the implantation of embryo into the front wall of uterus is not accompanied with increasing proliferation activity of endometrial cells of back wall of uterus.

While pregnancy continue the process of placentation starts and it is accompanied with decreasing of proliferation activity of endometrial cells of a back wall of uterus.The placentation into the front wall of uterus result in high level of endometrial cells death into the front wall of uterus.
