             "Viewer request Summarize the following paragraph: During such processes, cells sense the environment and respond to external factors that induce a certain direction of motion towards specific targets (taxis): this results in a persistent migration in a certain preferential direction. The guidance cues leading to directed migration may be biochemical or biophysical. Biochemical cues can be, for example, soluble factors or growth factors that give rise to chemotaxis, which involves a mono-directional stimulus. Other cues generating mono-directional stimuli include, for instance, bound ligands to the substratum that induce haptotaxis, durotaxis, that involves migration towards regions with an increasing stiffness of the ECM, electrotaxis, also known as galvanotaxis, that prescribes a directed motion guided by an electric field or current, or phototaxis, referring to the movement oriented by a stimulus of light [34]. Important biophysical cues are some of the properties of the extracellular matrix (ECM), first among all the alignment of collagen fibers and its stiffness. In particular, the fiber alignment is shown to stimulate contact guidance [22, 21].\n",
