      a process of tissue reorganization observed in many lower animals following severe injury, such as bisection of the animal, and involving the breakdown and reformation of cells, movement of organs, and redifferentiation of tissues. The result is usually a smaller but complete individual, derived entirely from the tissues of part of the original animal.
