  • Title: Delayed mast cell mediated mitogenic reactivity in diabetic rats.
    Author: Norrby K.
    Journal: Virchows Arch B Cell Pathol Incl Mol Pathol; 1982; 41(1-2):39-43. PubMed ID: 6134382.
    Abstract:
    Rats with diabetes of 4 weeks' duration have previously demonstrated increased mitogenesis in normal connective tissue cells following mast cell secretion. The appearance of this augmented mast cell-mediated mitogenic reactivity was studied in the mesentery of insulin-deficient rats, 3, 7, and 28 days after they had been rendered diabetic by a single dose of streptozotocin. On day 7 mast cell secretion induced a subnormal mitogenic response which, however, increased above normal on day 28. This time lag in the augmentation of mitogenic responsiveness may be important since proliferative lesions in diverse mesenchymal tissues typically develop with a similar delay in both experimental and clinical diabetes.
