Several signaling molecules are secreted from different domains in the embryo in order to specify the early somite to give rise to the sclerotome (SC) and the dermomyotome (DM). Wnt proteins are secreted from the dorsal neural tube (NT) and the surface ectoderm while Shh is secreted from the notochord (NC) and BMP4 from the lateral mesoderm plate. Altogether, these signaling molecules regulate the early myogenesis.
