MeSH definition : The founding member of the nodal signaling ligand family of proteins. Nodal protein
was originally discovered in the region of the mouse embryo primitive streak referred
to as HENSEN'S NODE. It is expressed asymmetrically on the left side in chordates
and plays a critical role in the genesis of left-right asymmetry during vertebrate
development.;
