Fig. 4 PTN97–110 affects angiogenesis in the zebrafish. (A) (a–d) Images illustrating the blood vessels at 72 hpf Tg(kdrl:GFP)s843 control and embryos injected with the zebrafish peptide, as seen from a left lateral. The dashed boxed regions are displayed at higher magnification in panels (a’-d’). (a’-d’) Higher magnifications of blood vessels in specified boxes. Injected embryos revealed a disorganized blood vessel arrangement in the head (c’), eye (c’’), ISV, and DLAV (d’’). Scale bar 200 μm. (e) Percentage of control and zebrafish PTN97-110 injected embryos with disorganized blood vessels. (B) (a–d) Images illustrating the blood vessels at 72 hpf Tg(kdrl:GFP)s843 control and injected embryos with the human peptide, as seen from a left lateral. The dashed boxed regions are displayed at higher magnification in panels (a’-d’). (a’-d’) Higher magnifications of blood vessels in specified boxes. Injected embryos revealed a disorganized blood vessel arrangement in the head (c’), eye (c’’), ISV, and DLAV (d’’). Scale bar 200 μm. (e) Percentage of control and human PTN97-110 injected embryos with disorganized blood vessels.
