(A) Effects of cinnamon extract exposure on zebrafish intersegmental vessels (ISVs). Zebrafish embryos were incubated in cinnamon extract for 16 h followed by incubation in fresh media stock for additional 24 h. (B) Summary of ISV length in 30 hpf (black bars) and 50 hpf (white bars) embryos exposed to DMSO (0 μg/mL), cinnamon extract at 150 and 250 μg/mL. (C) Zebrafish ISVs at 48 hpf imaged at 4× magnification. (D) Summary of ISV diameter in 48 hpf (black bars) embryos exposed to DMSO (0 μg/mL) and cinnamon extract at 250 μg/mL. GFP fluorescent signal of the ISVs of the transgenic zebrafish embryos was analyzed by fluorescent microscopy. ISVs are indicated by the red arrow. *P < 0.05.
