WebThe yolk sac mesoderm is a major site of hematopoiesis, and the yolk sac endoderm is the source of primordial germ cells. The yolk sac and its vitelline vessels provide temporary nourishment early in embryonic life. The nutritive role of the yolk sac is later taken over by the allantois, after the latter has developed. In developing embryos, blood formation occurs in aggregates of blood cells in the yolk sac, called blood islands. As development progresses, blood formation occurs in the spleen, liver and lymph nodes. When bone marrow develops, it eventually assumes the task of forming most of the blood cells for the entire organism. However, maturation, activation, and some proliferation of lymphoid cells occurs in the spleen, thymus, and lymph nodes. In children, haematopoiesis occurs in the …
