Fig. 2 The tnnc2 reporter is expressed by embryonic cardiomyocytes in zebrafish. (A–D) Confocal images (maximum intensity projections) of wholemount Tg(tnnc2:EGFP); Tg(myl7:DsRed2-NLS) hearts at 24 (A-A″), 36 (B–B″), 72 (C–C″) and 96 (D-D″) hpf. White arrowheads point to EGFP+ CMs around the atrioventricular (AV) and bulboventricular (BV) areas at 96 hpf (D–D″). Magenta asterisks mark craniofacial muscles. V: ventricle; At: atrium. Scale bars: 20 μm.
