What Role Do Stem Cells Play in Cell Proliferation?
Stem cells are pivotal in regulating cell proliferation. They serve as a reservoir for generating differentiated cells needed for tissue repair and regeneration. In the bone marrow, hematopoietic stem cells give rise to various blood cells, while mesenchymal stem cells in connective tissues can differentiate into bone, cartilage, and fat cells. The ability of stem cells to self-renew and differentiate is tightly regulated to ensure proper tissue function.
