What is Hyperplasia?
The increase in the number of cells within a normal tissue or organ, leading to enlargement of the affected area.
(self-eating) The process of disposing of nonfunctional organelles and sweeping up cytoplasmic bits by forming autophagosomes, which can then be degraded by lysosomes
