From: Micro RNAs are involved in activation of epicardium during zebrafish heart regeneration

Quantitative PCR regarding the relative expression of miRs in the epicardial cells (EPCs, light grey) and in regenerative clot (RC, black) of adult zebrafish at 1 (24 h) and 2 (48 h) dpa. (*) Statistically significant difference in the expression level in comparison to control (P < 0.001) according to the Student's t-test to a queue. Normalized values with U6 snRNA. (**) Values statistically significant (P < 0.001) EPCs vs RC
