Metabolic pathway regulating key stage of embryo development revealed  

Researchers showed that the mevalonate pathway is essential for embryonic development by promoting primitive streak formation, a key landmark for establishing embryo symmetry and gastrulation. The pathway induces farnesylation of lamin-B, which is implicated in inducing expression of primitive streak genes. The findings expand understanding of how embryos transition from a featureless ball of cells into a hollow, three-layered gastrula.
