To clarify the role of interferon-gamma (IFN-gamma) in reproduction, we have examined its effects on cytokine production by human endometrial stromal cells (ESC). Concentrations of interleukin (IL)-6, IL-8, monocyte chemoattractant protein-1 (MCP-1), and macrophage colony-stimulating factor (M-CSF) in the culture media of normal ESC and an endometrial stromal sarcoma cell line, MaMi, were measured using an enzyme-linked immunosorbent assay. Both non-stimulated ESC and non-stimulated MaMi cells constitutively secrete IL-6, IL-8, MCP-1, and M-CSF. In a dose-dependent manner, IFN-gamma increased the concentrations of IL-6, MCP-1, and M-CSF and reduced the concentrations of IL-8 in ESC and MaMi cells. These results suggest that IFN-gamma produced by both decidual inflammatory cells and the developing embryo plays a role in the maintenance of early pregnancy by modulating the production of these cytokines by human ESC.

Although preimplantation embryo and decidual cells secrete significant amounts of platelet-activating factor (1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine, PAF); its precise function in early pregnancy has yet to be established. To investigate the effect of PAF on cytokine synthesis, we measured the cytokine concentration in the culture media of two human cell lines: normal endometrial stromal cells (ESC) and endometrial stromal sarcoma cells (MaMi), following stimulation with a non-metabolized PAF analogue, carbamyl-PAF (C-PAF). Enzyme-linked immunosorbent assays were used to measure five cytokines: interleukin (IL)-6, IL-8, macrophage colony-stimulating factor (M-CSF), macrophage inflammatory protein-1alpha (MIP-1alpha) and tumour necrosis factor-alpha (TNF-alpha). We also evaluated the mRNA expression for IL-6 and IL-8 in ESC after C-PAF stimulation using Northern blot analysis. Non-stimulated ESC and MaMi cells both secreted IL-6, IL-8, and M-CSF, but not MIP-1alpha or TNF-alpha. The concentrations of IL-6, IL-8, M-CSF, MIP-1alpha, and TNF-alpha in the culture media of both cell lines increased in parallel with increasing amounts of C-PAF. C-PAF stimulated IL-6 and IL-8 transcription in ESC. These results suggest that PAF secretion by decidual tissues and developing embryos may induce cytokine synthesis by the ESC, as part of the cytokine network in the feto-maternal unit. An increase in the local cytokine concentration may be an important factor in the maintenance of early stages of gestation.

A T helper (Th)1/Th2 model has been applied to as a system regulating the cytokine network during pregnancy. To evaluate the effects of interleukin (IL)-4, a Th2 cytokine, on the cytokine production by endometrial stromal cells (ESC), an enzyme-linked immunosorbent assay was used to measure the concentrations of IL-6, IL-8, monocyte chemoattractant protein-1 (MCP-1), and macrophage colony-stimulating factor (M-CSF) in the culture media of ESC and of an endometrial stromal sarcoma cell line, MaMi, following the addition of recombinant human IL-4. The expression of mRNAs for IL-6 and IL-8 in ESC after stimulation with IL-4 was also evaluated by Northern blot analysis. Increases in the concentrations of IL-6, IL-8, MCP-1, and M-CSF in the culture media of ESC and MaMi cells were observed on the addition of increasing amounts of IL-4. This cytokine also stimulated the transcription of IL-6 and IL-8 in ESC in a dose-dependent manner. It is suggested that IL-4 secreted by the maternal decidual tissue as well as by the developing embryo may stimulate the production of IL-6, IL-8, MCP-1, and M-CSF by ESC. The increased concentration of these cytokines in the local environment may contribute to the maintenance of early pregnancy by modulating the immune reaction at the feto-maternal interface.
