"Quiescent cells" refers to cells in a quiet or resting state. These are cells that are not actively dividing or performing any specific tasks, but are still alive. It is like a pause or break for the cells before they resume their normal activities.
Full definition
Overgrown cultures stimulate quiescence, the resting phase of the cell cycle;
quiescent cells do not take up nucleic acid or express transgenes as well as actively dividing cells resulting in lower lentiviral titers.
In
a quiescent cell, like the one shown at right, the nucleus is intact and the chromosomes are a relatively indistinguishable mass of spaghettilike material.
Satellite cells are
quiescent cells that have to be activated in vivo before proliferating and differentiating into myotubes.

In contrast, loss of adhesion induced the phosphatases Dusp4 and -5 (Map - kinase phosphatases), which are inhibitors of the MAP - kinase signaling pathway, whereas contact inhibition induced
the quiescent cell - specific transcription inhibitor E2F4.
