Figure 1From: Quantitative evaluation and selection of reference genes in mouse oocytes and embryos cultured in vivo and in vitroIndividual expression profiles of selected reference genes in the in vivo derived embryos. The expression level in a particular developmental stage was represented with in vitro produced blastocyst embryo equivalent values, to show the relative amount. Stages with different letters are significantly (P ≤ 0.05) different for the expression of the gene.Back to article page
