Abstract:Monocyte chemotactic protein-1 (MCP-1) and interleukin-8 (IL-8) are important chemokines which effect the chemotaxis of monocytes and neutrophils, respectively. There is increasing evidence that such chemokines play an integral role in the control and maintenance of a normal pregnancy from implantation to parturition. However, little is known about the sites of secretion and function of MCP-1 and IL-8 in particular with respect to establishment of the placenta and membranes during first trimester. The aim of this study was therefore to investigate the concentrations and localization of MCP-1 and IL-8 in amniotic fluid and extra-embryonic coelomic fluid (EECF) collected by ultrasound-guided needle aspiration and maternal serum during the first trimester of pregnancy. Using specific enzyme-linked immunosorbent assays, MCP-1 was present at high concentrations in the EECF, significantly higher than those in amniotic fluid and maternal serum. IL-8 was also present predominantly in the EECF with concentrations being significantly higher than the low values detected in maternal serum and the very low amounts found in amniotic fluid. This strict compartmentalization of these cytokines in the fluid compartments of early pregnancy may be important for establishment and development of a viable pregnancy.
