title: Developmental biology: cell intercalation one step beyond.
abstract: Formation of the primitive streak, the equivalent of the blastopore, is a critical step during the early development of amniote embryos. Medio-lateral cell intercalation and the planar cell polarity pathway play a role during this earliest step of gastrulation in the chick embryo.
