Following statements are given regarding to the migration through primitive streak in chick.

A. Cells migrate to the primitive streak, and as they enter the embryo, the deep-moving cells give rise to the endodermal organs of the embryo, as well as to most of the extraembryonic membranes.

B. The migration of mesodermal cells through the anterior primitive streak and their condensation to form the chordamesoderm also appear to be controlled by FGF and Wnt signalling.

C. Wnt is expressed in the primitive streak and repels migrating cells away from the streak. 

D. Once cells migrate away from the streak, further movement of the mesodermal precursors appears to be regulated by FGF8 proteins.
