morfogener

Morfogener is a term found in some languages as a reference to agents or signals that influence the morphological development of an organism, typically in embryology. In standard scientific usage, the more common terms are morphogen or morphogenetic factor. When encountered, morfogener is often viewed as a direct translation or regional variant rather than a widely adopted label.

Etymology and usage context: The word combines morpho- (form, shape) with -gener (generator), suggesting a substance that generates or shapes form. In practice, morfogener tends to appear in non-English texts or as a calque in translations. Most scientific literature uses morphogen (or morphogenetic signal) to designate diffusible molecules that pattern tissues.

Biological role: Morphogens are substances that form concentration gradients within developing tissues and provide positional information to cells. Depending on local concentration, cells activate different gene expression programs, leading to orderly tissue and organ formation. Classic examples include signaling molecules such as Bicoid in Drosophila and Sonic hedgehog and Wnt proteins in vertebrates.

Terminology and scope: The term morfogener is not standard in major biology references. When used, it generally refers to the same concept as morphogen, though readers should consult local or language-specific sources. In Spanish, for example, the standard term is morphógeno, while in English the preferred term is morphogen.
