That means we lose around 50 million cells every day. This is a lot of skin cells to replace, making cell division in skin cells is so important. Other cells, like nerve and brain cells, divide much less often.
Skin cells need to divide as you grow. Hair follicle cells divide to produce more hair. Your lining cells (ex: stomach) and intestinal wall cells need to divide to provide new surfaces. Some cells like blood cells, nerve cells, and muscle cells do not divide after some time.
