What are some examples of cell specialization?

Examples of specialized cells include red blood cells, sperm cells, nerve cells, and muscle cells. Red blood cells originate from undifferentiated stem cells in the bone marrow. Sperm cells are produced in the male reproductive system within the testes via spermatogenesis. Nerve cells originate from neural stem cells, and muscle cells arise from myoblasts. It is important to note that it typically takes multiple rounds of cell division before they mature into specialized, fully differentiated cells.
