The term "post-mitotic"
is sometimes used to refer to both quiescent and senescent cells.
Nonproliferative cells in multicellular eukaryotes generally enter the
quiescent G0 state from G1 and may remain quiescent for long periods of
time, possibly indefinitely (as is often the case for neurons).
This is very common for cells that are fully differentiated. Cellular
senescence occurs in response to DNA damage or degradation that would
make a cell's progeny nonviable; it is often a biochemical reaction;
division of such a cell could, for example, become cancerous. Some cells
enter the G0 phase semi-permanentally e.g., some liver and kidney cells.
Example :
- Liver cells
- Kidney Cells
