Cellesubstitusjon
Cellesubstitusjon, also known as cell replacement or substitutional cell growth, refers to the process where one type of cell is replaced by another type of cell. This phenomenon can occur in various biological contexts, both during normal development and in response to pathological conditions. In developmental biology, certain progenitor cells may differentiate into a different cell lineage, effectively replacing the original cell type as an organism matures. This is a regulated and programmed event crucial for tissue formation and organ development.
Pathologically, sellesubstitusjon can be a response to injury, inflammation, or disease. For instance, in some chronic
