Entry term(s) nódulo de Hensen
organizador de Spemann
Scope note: Células de ciertas regiones del embrión que autorregulan el desarrollo embrionario. Estos organizadores han sido descritos en los polos ventral y dorsal de la GÁSTRULA y comprenden el organizador de Spemann de los anfibios y el nódulo de Hensen del pollo y del ratón. Estas células organizadoras se comunican entre sí vía una serie de proteínas señalizadoras segregadas como las PROTEÍNAS MORFOGENÉTICAS DEL HUESO y sus antagonistas (cordina y noggina).

Scope note: Cells in certain regions of an embryo that self-regulate embryonic development. These organizers have been found in dorsal and ventral poles of GASTRULA embryos, including Spemann organizer in amphibians, and Hensen node in chicken and mouse. These organizer cells communicate with each other via a network of secreted signaling proteins, such as BONE MORPHOGENETIC PROTEINS and their antagonists (chordin and noggin).
