What two sites are involved in the production and maturation of T lymphocytes? What hormone is secreted by the thymus and stimulates the maturation of lymphocytes into T cells? Thymosin (THIGH-moh-sin) is secreted by the thymus and effects the  maturation of T-cells.
The thymus produces hormone-like proteins that help T lymphocytes mature and differentiate. Some thymic hormones include thympoeitin, thymulin, thymosin, and thymic humoral factor (THF). Thympoeitin and thymulin induce differentiation in T-lymphocytes and enhance T-cell function.
