Question

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 help them treat individuals who suffer from spinal cord injuries. Provide reasoning to support the scientists’ prediction.

Answer 1

The data provides important information about the specific protein needed to induce cells to start the cell cycle, so to overcome an injury the cells need to divide and overcome the wound by repairing it, for this it will be necessary to deliver the appropriate protein to the cell. A new sign of how a protein inhibits the entry of cells into the cell cycle is also observed.
