The primitive streak—a structure that emerges in mammalian and avian embryos to help assign spatial information to cells during early development—has long been regarded as essential for the genesis of ...

the authors used two different methods to block the activity of the Wnt-PCP signalling pathway in the intercalation region of the chick embryo and showed that intercalation and primitive streak ...

The farnesylation of various proteins, including small G proteins and the nuclear protein Lamin B1, triggers primitive streak formation. Statins inhibit the induction of primitive streak genes by ...
