Fig. 4: METTL3 deficient mice displayed Cardiac left ventricular malformation.

A Schematic diagram of generating Mettl3f/f mice. B Western blotting analysis confirming the knockout efficiency of Mettl3 in the hearts from cKO mice. Gapdh served as an internal control. C Number of mice genotyped in pups and embryos when mating Mettl3f/f mice with Myh6-Cre transgenic mice. Representative HE staining of the hearts from cKO mice and control mice at E14.5 D-D’, E16.5 E-E’, E18.5 F-F’. D”, E”, F” Left wall thickness in cKO and control embryos were measured and calculated respectively.
