MiR-301a promotes embryonic stem cell differentiation to cardiomyocytes

Figure 1 MiR-301a is enriched in the heart of late-stage mouse embryo and neonatal mouse heart tissues. Tissues were collected from mouse embryos at days 11.5, 13.5, 15.5, and 17.5 and from 3-d-old postnatal and 6-wk-old adult mice. The expression level of miR-301a in the hearts was analyzed using quantitative real-time PCR. 5S rRNA was used for normalization. Data are presented as the mean ± SE (n = 3). ^aP < 0.05, ^bP < 0.01.
