  • Title: [Mast cells in rat lymph nodes].
    Author: Gheri Bryk S, Balboni GC.
    Journal: Boll Soc Ital Biol Sper; 1981 Mar 30; 57(6):651-5. PubMed ID: 7272036.
    Abstract:
    The histochemical and ultrastructural features of mastocytes have been studied in rat parathymic, para-aortic, inguinal and mesenteric lymph nodes. 1) In the parathymic lymph nodes, as well as in the lymph nodes of other sites in the body, all the stages of evolution of mastocytes may be detected, related to a progressive sulfation of the granular mucopolysaccharides. 2) It can be suggested that in the rat lymph nodes a genesis of mastocytes, probably from undifferentiated mesenchymal elements, might occur. No evidence have been found of a possible origin of mastocytes from lymphocytes. 3) The number of mastocytes and the extent of process of maturation of these cells in quite variable in relation to the different functional conditions of the lymph nodes.
