Question

The G₀ phase is a non-dividing phase in which cells remain metabolically active but do not divide. Some cells, such as neurons and osteocytes, remain in this phase permanently after differentiation. It is not an abnormal state, and cells can enter G₀ even in a healthy state. Cancer cells, on the other hand, tend to be in a highly proliferative state, so they would not typically be in G₀. While stem cells may enter G₀, it is not specific to those in the bone marrow.
