Can someone tell me some of the hypothesized causes of why a cell will enter into the resting G0 phase (that's, G-zero phase) during mitosis? My AP bio. textbook doesn't say why the cell will sometimes pause before DNA replication.
In vitro studies have examined the link between aberrant cell cycle reentry and neuronal cell death. These results demonstrate that although at least some postmitotic neurons retain the capacity to respond to growth factors by reentering into the cell cycle, such stimulation causes apoptosis rather than proliferation.
Cells often pause in G-1 before replication and enter a resting state called G-0 phase
Does anyone have examples of a few different cells that go into G0 Phase? It doesn't say in my text book and my class is suppose to find these examples for extra credit.
