Hensen's node expresses markers equivalent to:
Gene expression profile of chick Hensen's node determined by in situ hybridization and quail grafts mirrors amphibian organizer transcriptome: goosecoid homeobox, chordin BMP antagonist, noggin, FoxA2/HNF3beta and Sonic hedgehog axial signal. Both structures self-differentiate into notochord and prechordal plate while inducing neural plate. Nieuwkoop center expresses earlier beta-catenin and Siamois, animal pole cells ectoderm, vegetal pole endoderm not organizers. Molecular equivalence plus functional transplantation evidence confirms Hensen's node expresses markers equivalent to Spemann orga
