Abstract:
Abstract Studying the fine structure of the human fetal cndometrinm, we found simple and complex nuclear bodies in the epithelium.The estrogenic stimulation can enhance the formation and conversion of simplex nuclear bodies into complex nuclear bodies. Since the maternal estrogen and progesterone can enter the fetal blood stream through the placenta, we suppose that the formation of complex nuclear bodies in the fetal endometrial epithelium may be due to the stimulation of the maternal estrogen. The rRNA synthesized by complex nuclear bodies can elevate the protein synthesis for the cell proliferation of the endometrial epithelium.Because the formation of nuclear bodies can be prevented by progesteronic stimn tion, the presence of nuclear bodies in fetal endometrial epithelium may be related to the relative concentration of estrogen and progesterone circulating in the fetal blood stream and to the n mer of their receptors in the epithelium.
