Detailed explanation-1: -Proliferation and self-renewal of stem cells occurs via the division of a cell into two identical daughter cells, resulting in the production of cells identical to the parent. Unlike other cell types, such as muscle or blood cells, stem cells are able to replicate many times.

Detailed explanation-2: -Which of the following is true of stem cells? They can differentiate to produce many different kinds of specialized cells.

Detailed explanation-3: -Stem cells undergo cell proliferation to produce proliferating “transit amplifying” daughter cells that later differentiate to construct tissues during normal development and tissue growth, during tissue regeneration after damage, or in cancer.

Detailed explanation-4: -There are a few exceptions (e.g. liver cells or T-cells) but in general specialized cells can no longer divide. Skin cells, red blood cells or gut lining cells cannot undergo mitosis. Stem cells do divide by mitosis and this makes them very important for replacing lost or damaged specialized cells.
