The expression of mRNA of cytokines and immunoregulatory molecules characterizing the interaction of mesenchymal stromal cells from chorionic villi of postpartum placenta and allogenic mononuclear blood cells was studied during 3-day co-culturing of these cells. The expression of foxp3, il2ra, and il10 mRNA in floating mononuclear cells increased from day 1 to 3 in co-culture, which can refl ect the process of induction of regulatory T cells in the lymphocyte population under the action of mesenchymal stromal cells.

The concentrations of IL-10, IL-6, IL-1β, and TGFβ were measured.

Morphology, immunophenotypic characteristics, and differentiation potencies of isolated cells were studied. The capacity of mesenchymal stromal cells from extraembryonic tissues to osteogenic, adipogenic, and chondrogenic differentiation was demonstrated and the dynamics of this process was described.

The number of monocytes, macrophages (CD14+), and large granular lymphocytes (CD56+) in the endometrium increased in chronic endometritis. These changes are an unfavorable prognositic signs for the onset of pregnancy. Combination therapy improved the phenotypic composition of endometrial cells.

T lymphocytes with intracellular IFN-gamma prevailed in women with physiological course of the postpartum period. The number of cells containing IL-4 increased in patients with postpartum endometritis.

The ratio of peritoneal lymphocytes and macrophages in the peritoneal fluid was changed in endometriosis because of increased percentage of lymphoid cells and decreased content of macrophages, in the presence of high absolute counts of both types of cells. The cytokine status of women with endometriosis was characterized by higher levels of IL-1beta, TNF-alpha, and epidermal growth factors both in the peritoneal fluid and supernatants of 24-h cultures of peritoneal macrophages; the content of IFN-alpha remained unchanged.

The concentrations of cytokines (tumor necrosis factor-alpha and interleukin-10) in cervical scrapes and the percentage of CD4(+)lymphocytes producing interferon-gamma and interleukin-4 in the peripheral blood were measured in women of reproductive age with typical form of genital herpes. The results suggest that genital herpes is a chronic inflammatory process characterized by high levels of proinflammatory cytokines with predominance of T-helper type 1 over T-helper type 2 cytokines.
