Distinction From Senescent Cells
Although many cells in the G0 phase may die along with the organism, not all cells that enter the G0 phase are destined to die; this is often simply a consequence of the cell's lacking any stimulation to re-enter in the cell cycle.
Cellular senescence is distinct from quiescence because it is a state that occurs in response to DNA damage or degradation that would make a cell's progeny nonviable. Senescence then, unlike quiescence, is often a biochemical alternative to the self-destruction of such a damaged cell by apoptosis Furthermore, quiescence is reversible whereas senescence is not.

Famous quotes containing the words distinction from, distinction and/or cells:
“Let a man find himself, in distinction from others, on top of two wheels with a chain—at least in a poor country like Russia—and his vanity begins to swell out like his tyres. In America it takes an automobile to produce this effect.”
—Leon Trotsky (1879–1940)
“Let those talk of poverty and hard times who will in the towns and cities; cannot the emigrant who can pay his fare to New York or Boston pay five dollars more to get here ... and be as rich as he pleases, where land virtually costs nothing, and houses only the labor of building, and he may begin life as Adam did? If he will still remember the distinction of poor and rich, let him bespeak him a narrower house forthwith.”
—Henry David Thoreau (1817–1862)
“They are sworn enemies of lyric poetry.
In prison they accompany the jailer,
Enter cells to hear confessions.
Their short-end comes down
When you least expect it.”
—Charles Simic (b. 1938)
