Figure 4From: Expression profiles of the pluripotency marker gene POU5F1 and validation of reference genes in rabbit oocytes and preimplantation stage embryosRelative expression levels of the POU5F1 gene in the in vitro produced preimplantation stage rabbit embryos. The expression at the oocyte stage was taken as a reference to calculate the relative levels of the other stages. Stages with different letters are significantly (P ≤ 0.05) different for the levels of the gene.Back to article page
