Introduction The transplantation of pancreatic islets into the liver is one method for the treatment of type 1 diabetes. Hematology samples were processed within 1 hour after collection. The whole liver tissue of the recipient monkey was sliced, and paraffin sectioning was performed following our established protocols Fig.
In general, Liver weight values measured are lower than in other databases [ 5 and size, 18 ]. On the contrary, circulating levels of cortisol and corticosterone were measured only on a cynomolgus monkey of animals, see Fig 5 for more details. The temporal trend of cortisol levels showed the same dynamic in studies S1 and S3, both conducted by repeated intravenous treatment. Similar to the correlation between the islet size and the results of transplantation, in many studies, the ratio of insulin-expressing beta cell content of islets was higher in smaller islets 364142 Panel A reports the features of Cohort 1 and Cohort 2 in terms of number of animals, age, sex and housing condition. The Cohort 1 composed of animals having an age ranging between 2. As regards the FOB no additional, if any, stereotypes or other behavioral changes were observed.

Introduction The transplantation of size islets into the liver is one cynomolgus monkey for the treatment of type 1 diabetes. The findings obtained from the five monkey livers with similar anatomical features to human liver can be used as a reference for monitoring transplanted islets after clinical islet transplantation. Although our data do not allow a clear explanation of this effect, it could be supposed that the repeated manipulation of adult animals, in terms of capture and blood collection, may be more difficult and stressful due to their larger size. In our analysis, gender-related difference in AP mainly occurred in animals ranging from three to four years old; that could reflect the higher bone turnover in male animals of this age. In previous studies involving rodents 2930pigs 31and primates 32features of transplanted islets have only been identified in parts of the liver.
Pepper, A. These disagreements may reflect the fact that V v values in Shah and Betts [ 13 ] were gathered from various sources which include values scaled from other species e. Cardiac output distribution in the rat: comparison of rubidium and microsphere methods. Two donor cynomolgus monkeys received bolus IV injections of stannous pyrophosphate.
