metaphase
Cells that are no longer undergoing mitosis are typically in the G0 phase of the cell cycle. This is a resting phase where cells are not actively dividing but still carry out their normal functions. Cells can remain in this phase for extended periods or resume the cell cycle in response to certain signals.
The three types of cells that enter the G0 phase when they are mature are neurons, muscle cells, and certain types of immune cells like memory B and T cells. These cells have exited the cell cycle and are in a resting phase, performing their specialized functions without actively dividing.
Shortly after childbirth, nerve cells (neurons) stop reproducing. Therefore, nerve cells are not undergoing mitosis at all; rather, they are in the G0 phase. During the G0 phase, no preparations are made for cell division: the cell simply lives. While nerve cells do not reproduce, they do form connections between each other, establishing a more complex network as time passes.
The G0 phase (referred to the G zero phase) is a period in the cell cycle in which cells exist in a quiescent state. G0 phase is viewed as either an extended G1 phase, where the cell is neither dividing nor preparing to divide, or a distinct quiescent stage that occurs outside of the cell cycle. G0 is sometimes referred to as a "post-mitotic" state, since cells in G0 are in a non-dividing phase outside of the cell cycle. Some types of cells, such as nerve and heart muscle cells, become post-mitotic when they reach maturity (i.e., when they are terminally differentiated) but continue to perform their main functions for the rest of the organism's life. Multinucleated muscle cells that do not undergo cytokinesis are also often considered to be in the G0 stage. On occasion, a distinction in terms is made between a G0 cell and a 'post-mitotic' cell (e.g., heart muscle cells and neurons), which will never enter the G1 phase, whereas other G0 cells may.

Cells are made in the bone marrow in the body. This process is called hematopoiesis, where stem cells differentiate into various types of blood cells such as red blood cells, white blood cells, and platelets.

The cells in G0 phase do not go through mitosis whatsoever. These cells only do what they are initially suppose to do, and do not prepare for a division. Many cells in your body are like this. Brain cells are in G0 phase and do not EVER replace itself. However, many cells may also trigger its phase from G0 phase to G1 phase when more cells are needed. When a liver is critically damaged, the liver cells are triggered back to G1 phase to replenish its lost cells. When this is complete, it goes back to being in G0 phase.
All phase specific types are by definition cell cycle specific? But does it work the other way around? (i.e. are there any types that are only cell cycle specific but not phase dependent?) Would like to now about the four main types of chemo. Alkylating agents - cell cycle independent Mitotic inhibitors - phase dependent? Topoisomerase inhibitors - both phase dependent and/or cell cycle dependent? Antimetabolites - phase specific?
