intracellular

Within cell boundaries

Intracellular means within a cell or cells: intracellular fluid, intracellular signaling.

The term appears in biology and medicine to describe processes, structures, or substances located inside cell membranes rather than between cells (intercellular) or outside them (extracellular).

The virus replicates through intracellular mechanisms.
