Inhibition of carboxypeptidase activity causes vascular defects. (A,B) Bright-field images of untreated control and embryos treated with 0.01 mg/ml protamine, a carboxypeptidase inhibitor. (C–F) The protamine-treated embryos showed stalling of ISVs (D) and mispatterned CVP (F) compared with completed growth of ISV (arrowheads in C) and the sprouting or loop structure of CVP (E) in wild-type embryos at 30 hpf. (E) The quantification of complete ISVs in embryos treated with 0.01 mg/ml protamine (18 ± 7%, n = 10) and untreated controls (92 ± 3%, n = 10). The data shown is representative of two independent experiments. Data are represented as means ± S.D. ***Refers to p < 0.0001 by an unpaired Student’s t-test. Scale bars are 200 µm for A-B and 100 µm for C-F.
