-  This term was made obsolete because it describes involvement of the nodal signaling pathway in lateral mesoderm left/right asymmetry. Nodal proteins are members of the TGF-beta superfamily, but are distinct from TGF-beta proteins themselves. TGF-beta proteins are not currently known to regulate left/right asymmetry in the lateral mesoderm.
