| Abstract: | Modern molecular biological studies have significantly improved understanding of structural and functional organization of the female reproductive system. The paper gives a brief overview of the literature and own research on verification and expression in the endometrium and placenta of many peptides, biogenic amines, steroids, cytokines and other signalling molecules, which, acting as hormones, enzymes, inhibitors, receptors, growth factors, immunoregulatory agents, transport's and binding proteins, provide the local regulation of intercellular neuroimmunoendocrine relationships that play a key role in the mechanisms of human embryogenesis and reproduction. |
