Syndecan-1 Acts as an Important Regulator of CXCL1 Expression and Cellular Interaction of Human Endometrial Stromal and Trophoblast Cells

Figure 4

Quantitative analysis of CXCL1 protein secretion (%) of human EnS cell lines St-T1 and KdS1 measured by ELISA. (a + b) St-T1, dSt-T1, KdS1, and dKdS1 were treated with indicated concentrations of the inhibitors for 2 h, and subsequently the cells were incubated with IL-1β for 48 h (10 ng/mL for nondecidualized and 0.1 ng/mL for decidualized cells). Shown are means ± SD with for treated cells versus untreated cells. Cells with no inhibitor but IL-1β treatment served as controls (0) (=100% CXCL1 secretion); 0/0 cells (no inhibitor, no IL-1β) served as secretion controls (=0%).
