All cells in the body, excluding sex cells, use mitosis for division. These cells are known as non-reproductive cells or somatic cells. Somatic cells constitute various parts of the body including connective tissue, bones, internal organs, skin, and blood. Some examples of these cells include blood cells, skin cells, nerve cells, and muscle cells. Adult stem, also known as somatic stem cells, also use mitosis for cell division. This is crucial for regenerating and replenishing specialized cells in tissues. As examples, stem cells are located in the brain, liver, bone marrow, and the digestive system.
