Abstract
Extra-embryonic tissues assist development but aren’t part of the embryo body, for example zebrafish YSL and mammalian placentas. Zebrafish YSLs form during early cell divisions when membranes of marginal blastomeres retract, forming a multinucleated layer. YSLs can grow abnormally, associated with specific gene defects. Studying what causes these defects to arise during YSL development can aid understanding of healthy embryonic development, and could be used as a model organism to better understand mammalian development.
