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).
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.
