Molecules that impart positional information and promote developmental changes at the cellular level are most accurately referred to as morphogens.

What are morphogens ?

Developmental biology places a lot of importance on the idea of "morphogens." A morphogen is, by definition, a chemical that emerges from a particular group of cells, is present in a gradient of concentration, and determines the fate of every cell along the gradient.

Morphogens are substances that create a graded distribution and cause various cellular reactions that are dose-dependent. They serve to convey positional information to individual cells within a field, which is then interpreted to produce spatial patterns.
