Thymocyte selection

A thymocyte is an immune cell present in the thymus, before it undergoes transformation into a T cell. Thymocytes are produced as stem cells in the bone marrow and reach the thymus via the blood. Thymopoiesis describes the process which turns thymocytes into mature T cells according to either … Visa mer Thymocytes are classified into a number of distinct maturational stages based on the expression of cell surface markers.
