Detailed explanation-1: -When the cells undergo oriented mitotic division to repair the wound by natural process, the impaired skin can complete perfect repair; and when the cell division orientation is random, there will form fibre hyperplasia, abnormal tissue structure and eventually lead to scar formation.
Detailed explanation-2: -Why do skin cells reproduce faster than other types of cells? Because the skin cells prevent germs from coming in our bodies. Skin cells are very easily removed, so it needs to reproduce faster.
Detailed explanation-3: -But some cells, such as skin cells or blood cells are dividing all the time. When cells become damaged or die the body makes new cells to replace them. This process is called cell division.
Detailed explanation-4: -In the late stages of cancer, cells break through normal tissue boundaries and metastasize (spread) to new sites in the body.
