Morphogen - Wikipedia
A morphogen is a substance whose non-uniform distribution governs the pattern of tissue development in the process of morphogenesis or pattern formation, one of the core processes of developmental biology, establishing positions of the various specialized cell types within a tissue. More specifically, a morphogen is a signaling molecule that acts directly on cells to produce specific cellular responses depending on its local concentration. Typically, morphogens are produced by source cells and diffuse through surrounding tissues in an embryo during early development, such that concentration gradients are set up. These gradients drive the process of differentiation of unspecialised stem cells into different cell types, ultimately forming all the tissues and organs of the body. The control of morphogenesis is a central element in evolutionary developmental biology (evo-devo). The term was coined by Alan Turing in the paper "The Chemical Basis of Morphogenesis", where he predicted a chemi
From Wikipedia, the free encyclopedia Morphogenesis of Drosophila fruit flies is intensively studied in the laboratory A morphogen is a signaling molecule that contributes to morphogenesis and pattern formation, which are key processes in developmental biology.[1] Morphogens help organize tissues by creating spatial and temporal differences in signaling activity. They are typically defined as signals that generate distinct cellular responses across a population of cells.[1][2] These responses depend on several factors, including signal concentration and the duration of exposure. They are…
