A Summary of Various Forms of Physical and Chemical Stimuli, Gradients of Which Are Known to Provide a Control Over Cell Movement or “Taxis” (Adapted from Lo et al.³ and Haga et al.⁴)

Stimulus
Type	Form	Form of “-taxis”
Chemical	Dissolved form	Chemotaxis
	Immobilized form	Haptotaxis
Physical	Substrate rigidity	Durotaxis/mechanotaxis
	Electrostatic potential	Galvanotaxis
	Light intensity	Phototaxis
	Gravitational potential	Geotaxis
	Extracellular tension	Tensotaxis
