Fig. 7

Myh6 expression is lost in venous atrial cardiomyocytes of nr2f1a;isl1 mutants. (A) Schematic of lineage tracing of Myh6⁺ cells within the hearts of wild-type and nr2f1a^−/−;isl1^−/− embryos. (B-E″) Optical sections of the venous heart in wild-type and nr2f1a^−/−;isl1^−/− embryos at 96 hpf (B-C″) and 120 hpf (D-E″) stained for Myh6 (blue) and myl7:ZsYellow (green). (B-E″) Myh6⁺/ZsYellow⁺ cells (white arrows). (C-C″,E-E″) Myh6⁻/ZsYellow⁺ cells (yellow arrows). Scale bars: 10 μm. 96 hpf: wild type (n=2) and nr2f1a^−/−;isl1^−/− (n=13). 120 hpf: wild type (n=7) and nr2f1a^−/−;isl1^−/− (n=9).
