Figure 3From: The chemokine receptor CXCR4 and its ligand CXCL12 are activated during implantation and placentation in sheepCXCL12 and CXCR4 mRNA is upregulated in conceptuses during early gestation. CXCL12 (A) and CXCR4 (B) mRNA are significantly (P < 0.05) upregulated in ovine conceptuses on Day 21 compared to earlier days collected. Both CXCL12 and CXCR4 transcripts are also significantly (P < 0.05) upregulated on Day 30 of pregnancy compared to Days 13, 15, 16, 17, and 21. Data are represented by graphing 2-ΔCt values, where ΔCt indicates GAPDH normalized Ct values. Data represent the mean ± SEM.Back to article page
