Fig. 2 VE-Cad MO splice-blockade also impairs formation of circulation and results in pericardial edema and improper cardiac looping.
Brightfield images of embryos injected with VE-Cad splice-blocking morpholino (VE-Cad spMO) also show impaired circulation, pericardial edema and impaired cardiac looping (c–d, g–h), when compared to controls (a–b, e–f). Assessments of cardiovascular phenotype: (i) circulation was assessed in VE-cad tMO, spMO and control MO embryos, with VE-cad MO injected embryos demonstrating impaired circulation at all time points. (j) Pericardial edema was highly prevalent in VE-cad MO injected embryos. (k) Cardiac looping in the two groups, with abnormal looping more frequent in the VE-cad MO fish (n = 150–200 embryos per group).
