One of the major benefits of using the zebrafish as a model system is the transparency of its developing embryos. Couple with transgenesis, this makes it possible to visualize developing blood vessels in vivo. Below are links to some pictures of developing blood vessels in zebrafish embryos.

- ventral view of Tg(fli1:egfp) larva at day 7 of development. Jaw cartilage, blood vessels and the heart can be seen in green fluorescence
