Results: At 20 [micro] M, rhein could almost completely block intersegmental blood vessels formation at both 48 and 72 hpf, and completely inhibit subintestinal vessel plexus formation at 72 hpf.
For better documentation of the blood vessels in embryos, Tg(fiila:EGFP)y1 zebrafish embryos were used to observe the Enhanced Green Fluorescent Proteins (EGFPs) which are expressed in all endothelial cells of the vasculature in intersegmental blood vessels (ISVs) and subintestinal vessel plexus (SIVs) at 48 and 72 hpf, respectively, after drug treatment at 24 hpf (Lawson and Weinstein 2002; Raghunath et al.
The ISVs and subintestinal vessel plexus (SIVs) are the most easily observed angiogenic vessels in zebrafish embryos at 48 and 72 hpf, respectively.
