MeSH definition : Members of the transforming growth factor superfamily that play a role in pattern
formation and differentiation during the pregastrulation and GASTRULATION stages of
chordate development. Several nodal signaling ligands are specifically involved in
the genesis of left-right asymmetry during development. The protein group is named
after a critical region of the vertebrate embryo PRIMITIVE STREAK referred to as HENSEN'S
NODE.;
