Quiescence refers to a reversible G0 state where subpopulations of cells reside in a ' quiescent' state before entering the cell cycle after activation in response to extrinsic signals .

The G0 phase describes a cellular state outside of the replicative cell cycle. Classically, cells were thought to enter G0primarily due to environmental factors, like nutrient deprivation, that limited the resources necessary for proliferation. Thus it was thought of as a resting phase. It's now known that G0 cannot be painted with a single broad brushstroke. For example, most adult neuronal cells, among the most metabolically active cells in the body, are fully differentiated and reside in a terminal G0 phase. Neurons reside in this state, not because of stochastic or limited nutrient supply, but because it's part of their internal genetic programming.
