Figure Caption

Fig. 2 syk^LO and zap-70^LO morphants display late stage ISV patterning defects. (A) The trunk of 5 dpf wild-type Tg(fli1a:EGFP)^y1 embryos display regularly patterned ISVs between somites, with the dorsal-most ISV endothelial cell forming a clear T shape and contributing to the DLAV. In contrast, 5 dpf syk^LO (B), zap-70^LO (C), and syk^LO:zap-70^LO (D) morphants display abnormal ISV vasculature with mild patterning defects. The ventral stalk ISV endothelial cell is relatively normal, and the dorsal T-cell still contributes to the DLAV, but the branching of the cell into the T shape is abnormal (asterisks) and can occur as ventrally as midsomite (arrows). These dorsal patterning defects are more pronounced in the syk^LO:zap-70^LO morphants.
