Amitosis, also known as karyostenosis, direct cell division, or binary fission, is a mode of asexual cell division primarily observed in prokaryotes.This process is distinct from other cell division mechanisms such as mitosis and meiosis, mainly because it bypasses the complexities associated with the mitotic apparatus, such as spindle formation.
These neurons re-enter the cell cycle as they travel to the ganglion cell layer when they are activated by p75NTR. These neurons are unable to enter mitosis and are stuck in a 4C DNA content state. Cell cycle re-entry by p75NTR is not dependent on Cdk4/6 (Morillo et al., 2012) and, therefore, differs from other cell types that re-enter the cell ...
For example, most adult neuronal cells, among the most metabolically active cells in the body, are fully differentiated and reside in a terminal G 0 phase. Neurons reside in this state, not because of stochastic or limited nutrient supply, but as a part of their developmental program.
The amitotic or mitotic cell divisions are more atypical and diverse among the various groups of organisms, ... The most important being the G 1-S transition ...
The nucleus is the source of most of the RNA that is produced in neurons. In general, most proteins are produced from mRNAs that do not travel far from the cell nucleus. This creates a challenge for supplying new proteins to axon endings that can be a meter or more away from the soma.
