The elongation of heart tube was normally developed at 24 hpf in the wild-type (A) and in the morphants (C); whereas the heart of morphant did not elongate to from a heart-tube (B). The wild-type (D) and morphant's heart (F) developed normally at 30 hpf, but the heart of morphant was still retardant development at 30 hpf (E), and even ceased at heart-cone stage at 36 hpf (F). Compared to the wild-type (G), however, the heart positioning was abnormally in the morphant at 36 hpf (I, J). Eventually, both and morphants displayed an unlooped and stretched heart (L, M). The heart morphology of embryos injected with the control MO was also observed at 72 hpf (N). a: atrium; v: ventricle

Tg() embryos were injected with -MO and observed by two-photon fluorescence imaging of a live transgenic zebrafish heart at 100 hpf. The endocardial cells and blood are labeled yellow; the Hc-GFP-positive myocardial cells are labeled red.
