Neurons (nerve cells) of the central nervous system (brain and spinal cord) are in g0 of the cell cycle and generally do not divide in response to an injury. the scientists predict that they can use the data from this experiment to them treat individuals who suffer from spinal cord injuries. provide reasoning to support the scientists' prediction.

Neurons are the fundamental unit of the central nervous system. Nerve cells are present in the brain and spinal cord of the human body.

The nerve cells cannot be reproduced in the case of injury because :

During the cell cycle, the cell undergoes interphase, M phase, and cytokinesis. The G0 phase of the interphase is the stage in which cell the cell is in the resting phase.

It is the stage in which the cell neither divides nor replicates. The neurons on maturity lose the ability to replicate and produce daughter cells because they exist in the G0 phase of the cell cycle.

Thus, it explains that during trauma or an injury situation, the damaged neurons will not be regenerated and cannot be replaced. The path of neurons once destroyed cannot be recovered.

The new path is then created to restore the normal functionality of nerves, known as neuroplasticity.

Therefore, the neurons exist in the G0 phase, which makes them unable to prepare or divide for further purposes.

The reasoning proposed to sustain that Neurons can't reproduce in the case of an injury to attend it is that G0 state of the cell cycle is a stage in which the cell is not preparing itself to divide or will prepare itself to divide.

Explanation:

To understand this answer we need to analyze the context and the proposition. First of all the G0 cell state level is a stage in which the cell is not preparing for division and is not going to prepare itself to divide, so this describes perfectly how neurons won't prepare to reproduce in case an injury is suffered. This trauma situation is a pivot to elaborate on different treatment strategies to restore the functionality of the neuron tissue. Because even though they are damaged they don't recover that way of communicating and need to create another path. This is called neuroplasticity. even though this is a perfect basic piece of knowledge breaking research has found out that neurogenesis is produced but we don't know yet how.
