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.
