vegfab is not involved in early cardiovascular development in zebrafish. (A) Open boxes and black lines denote exons and introns of the early coding and non-coding region of vegfab. MO in red mark the target sites of the vegfab translation blocking. P1 and P2 indicate the sites of primers; (B) Fragments of vegfab sequences were amplified using the indicated primers. In vegfab morphant embryos, the normal vegfab RT-PCR product was not detected (lane 3). β-actin cDNA was also amplified from each sample as an internal control; (C,D) The expression of vegfab during early embryogenesis cannot be detected. Scale bar: 200 μm (C); 500 μm (D); (E) The heart development is almost normal with 10ng doses of vegfab MO at 96 hpf under the background of Tg(myl7:mCherry)/Tg(kdrl:EGFP) transgenic fish. Scale bar: 50 μm.
