More specifically, a morphogen is a signaling molecule that acts directly on cells to produce specific cellular responses depending on its local concentration. Since morphogens diffuse through the tissues of an embryo during early development, 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.ince morphogens diffuse through the tissues of an embryo during early development, concentration gradients are set up.
