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. The earliest thymocyte stage is the double negative stage (negative for both CD4 and CD8), which more … Visa mer Thymus settling Thymocytes are ultimately derived from bone marrow hematopoietic progenitor cells [see hematopoietic stem cell, hematopoiesis] which reach the thymus through the circulation. The number of progenitors that … Visa mer Thymocytes that gain oncogenic mutations allowing uncontrolled proliferation can become thymic lymphomas.
