Which cells are in g0 phase?
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.
