BackgroundZebrafish, Brachydanio rerio, have a distinct embryonic development. The embryo goes through a process called epiboly. Epiboly, as defined in the sixth edition of Developmental Biology(Gilbert 2000), is the movement of epithelial sheets (usually of the ectoderm cells) that spread as a unit, rather than individually, to enclose the deeper layers of the embryo. Epiboly enables an embr......阅读全文
