Cellular proliferation refers to which process?

• A. The death of cells
• B. The differentiation of cells
• C. Migration of cells
• D. The multiplication or reproduction of cells

Answer: (D)

Cellular proliferation describes the multiplication or reproduction of cells—an increase in cell number produced by cell division. This is the growth-related process that adds new cells to tissues during development, growth, and repair. It’s distinct from differentiation, which is about cells gaining specialized functions; from migration, which is about cells moving to a new location; and from cell death, which reduces the number of cells. For example, after a skin wound, cells divide to restore the tissue, illustrating proliferation in action.
