Fig. 1From: Identification of reference genes for gene expression studies among different developmental stages of murine heartsFlow chart of the study design. Illustration of the developmental stages of the mice left ventricle tissues sampled in this study and the short description of the core experiment manipulations. The statistical applications for evaluating the expression stability of reference genes were also shown. E = embryonic day; D = postnatal day; M = postnatal monthBack to article page
