Chemotaxis can be defined as the growth or movement of motile organisms or cells guided by a chemical gradient. It can either be positive (towards the chemical) or negative (away from the chemical)[1].

This may involve contact guidance, where the organism or cell attaches to other cells within it's vicinity, for a short time, to move towards it's destination. Once it's completed it's journey, the organism or cell will need to assemble or adapt itself within it's new environment[2].
