Quizplus · Accepted Answer

Cells that do not ordinarily divide, such as muscle and nerve cells, may be useful to repair damaged tissues. However, promoting cell division in these cells could also lead to cancer. Therefore, understanding how to promote cell division in a controlled and safe way could have potential applications in regenerative medicine.
