T cells or T lymphocytes are a type of lymphocyte (in turn, a type of white blood cell) that plays a central role in cell-mediated immunity. They can be distinguished from other lymphocytes, such as B cells and natural killer cells (NK cells), by the presence of a T-cell receptor (TCR) on the cell surface.
Thymus. T cells mature out of stem cells produced in the bone marrow and transported into the thymus. They emigrate out of the thymus, colonizing the secondary lymph organs, and are active there as immunocompetent cells for the defense of the body against infections. The thymus derives from the foregut out of the 3rd and 4th pharyngeal pouches.
