Expression of Egf receptors and their ligands in medaka tissues and embryonic stem cells. A) Expression of egfra and egfrb, B) egf, C) tgfa, D) hbegf, E)epgn , F)ereg, G)areg and H) btc in adult medaka tissues or organs, and in medaka stem cells. Values for each gene were normalized to expression levels of elongation factor 1 alpha 1 (ef1a1) using the 2-DDCT method [52]. Expression in brain was set as reference (value: 1); Data are presented as mean ± standard deviation of three independent quantitative real-time PCR experiments.
