Abstract:
Differentiation of the hematopoietic tissue is controlled by growth factors which act precisely on stem cells arriving at a specific stage of differentiation. The recent identification of retinoic acid, a vitamin A metabolite, as an active differentiating agent of acute promyelocytic leukemia, has allowed to define a normal group of growth and differentiation factors of the myeloid tissue: vitamins A and B and thyroid hormones.
