Figure Lengend Snippet: M1-Mφ-derived CXCL9 impairs trophoblasts invasion and migration. (A) mRNA expression levels in HTR-8 cells cultured alone or co-cultured with M1-Mφ. (B) ELISA assays of CXCL9 in the supernatant of M1-Mφ alone or co-cultured with HTR-8 cells. (C) CXCL9 mRNA expression in HTR-8 and M1-Mφ with or without 48 h of co-culture. (D-F) The expression of EMT markers in HTR-8 cells alone, CXCL9-supplemented HTR-8 cells, M1-Mφ-co-cultured HTR-8 cells, and anti-CXCL9 M1-Mφ-co-cultured HTR-8 cells were analyzed by qPCR, western blot and immunofluorescence. Scale bar: 20 μm. (G, H) Migration and invasion of anti-CXCL9 M1-Mφ-co-cultured HTR-8 cells and its control were measured by wound-healing assay and transwell assays, respectively. n = 3, Scale bar: 50 μm; * P < 0.05, ** P < 0.01, *** P < 0.001.
Article Snippet: In the anti-CXCL9 group, anti-Mouse CXCL9/MIG Antibody (1 mg/kg; MCE, Shanghai) were injected into female C57BL/6 mice by intravenously administered at 8:00 am on E7.5, E10.5 and E13.5.
