  • Title: Islet cell transplantation in diabetic dogs: studies of graft function and storage.
    Author: Alderson D, Walsh TN, Farndon JR.
    Journal: Br J Surg; 1984 Oct; 71(10):756-60. PubMed ID: 6435717.
    Abstract:
    Islet cell transplantation is a potential treatment for insulin-dependent diabetes (IDD), assuming that physiological hormone release results in biochemical normality which, in turn, reduces the incidence of long-term diabetic complications. These experiments sought to create a metabolic model of IDD in a large animal and investigate the effects of insulin therapy and islet transplantation. After demonstrating the success of transplantation, further studies examined the feasibility of creating multiple grafts from a single donor and their long-term preservation. The totally pancreatectomized dog, treated with suboptimal insulin therapy was biochemically identical to human IDD and, when more appropriate doses of insulin were administered, metabolic improvements occurred without restoring normality. Islet cell autotransplants rendered such animals metabolically normal apart from persisting impairment of glucose tolerance. The isolation technique permitted the production of at least two recipient grafts and some success was achieved after graft cryopreservation. The experiments confirm the theoretical background to islet transplantation and demonstrate its applicability in a large animal model before allotransplantation.
