somatic
pertaining to the body, for example, somatic mutation in which a stable gene change occurs in a body cell rather than in a germ (reproductive ) cell

Somatic Cells
A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent.
