during gastrulation, what type(s) of cells is/are visible if you were to observe the development through a window cut in the shell of the egg? Include a diagram.

Expert Solution

Gastrulation is a dynamic process that involves critical change in the embryo such as differentiation of cells,establishment of three primary germ layers and transformation of single walled blastula into double walled grastula.

Following structure are visible in window cutting:-

1.Forrmation of endoderm.

2.Formation of embryonic disc and mesoderm

3.Formation of ectoderm

You perform the following experiment: Xenopus embryos are treated early in development (before gastrulation begins) with morpholinos to reduce the activity of Cerberus. You take an explant from the dorsal blastopore lip from a normal embryo at the beginning of gastrulation cell movements and inject it into the blastocoel of a normal host embryo. You then take a dorsal blastopore lip explant from a Cerberus 'morphant' (morpholino injected) embryo and transfer it into the blastocoel of a normal host embryo....
