Figure 1From: Expression profiles of the pluripotency marker gene POU5F1 and validation of reference genes in rabbit oocytes and preimplantation stage embryosRelative expression levels of selected candidate reference genes in the in vivo derived rabbit embryos. The expression level 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
