Figure 2From: Bovine trophoblastic cell differentiation and binucleation involves enhanced endogenous retrovirus element expressionERV elements were expressed in the BT cell lines. The expression levels of four ERV elements, bERVE-A, bERVE–B, BERV-K1 env, and BERV-K2 env, in BT cell lines (BT-1, BT-A to BT-L), cotyledonary and endometrial fibroblast cells (CF and EF), and bovine endometrial epithelial cells (BEE) were analyzed by qRT-PCR, and the results were normalized to GAPDH mRNA expression. The bar graph shows mean ± SEM values. Data labeled with different letters are significantly different from each other (P < 0.05).Back to article page
