AbstractThe study of the cytological evolution of the foetal thymus enables us to distinguish an early foetal period (up to 20 weeks) from a late foetal period. The cytological maturation is achieved at 20 weeks of gestation. The thymus in the late foetal phase is comparable to that of the child.The study of the lymphopoietic function shows a higher activity in the foetal thymus up to 20–22 weeks, lymphopoiesis is also slightly increased, in the thymus of the child up to the age of three years. The study of the contribution of the various cell types to the cellularity of the thymus, emphasizes the importance of the medium lymphocytes in the early foetal period. The small lymphocytes though to a lesser extent, are also capable of division in the foetal thymus and in the infantile thymus. Incorporation of uridine is also increased in the early foetal thymus.Cytological composition and lymphopoiesis of the foetal thymus and lymph node, have been compare
