Figure 4From: The chemokine receptor CXCR4 and its ligand CXCL12 are activated during implantation and placentation in sheepUpregulation of mRNA for CXCL12 and CXCR4 on Day 35 compared to Day 50 of pregnancy in cotyledon (Cot), caruncle (Car) and intercaruncle (Intercar) tissue. CXCL12 (A) was significantly (P < 0.05) greater in cotyledon tissue on Day 35 compared to Day 50 of gestation. CXCR4 (B) was significantly (P < 0.05) elevated in caruncle and intercaruncle tissue on Day 35 compared to Day 50 of pregnancy. Data represent 2-ΔCt values, where ΔCt indicates GAPDH normalized Ct values. Data represent the mean ± SEM.Back to article page
