“…Initial studies indicated that the isolation procedure was generally more complicated and yielded considerably fewer islets than in laboratory animals, a finding that agrees with previous reports in the literature (11)(12)(13)27). The results were also related to donor age in that only pancreatic glands obtained from donors below 45 yr of age yielded satisfactory islets.…”

“…The tissue insulin and amylase content are presumably proportional to B-cell mass and exocrine cell content, respectively; therefore, insulin/amylase ratio reflects the purity of islet cell mass relative to exocrine cell contamination. 8 - 13 A 57% recovery of B-cell mass was suggested by insulin recovery. Approximately a sixfold purification of B-cell content was noted.…”
“…A minimal effect on diabetes has been observed after transplantation of isolated islets to the peritoneal cavity of totally pancreatectomized pigs [98] or to the portal vein of monkeys made diabetic either by partial pancreatectomy and streptozotocin [85] or total pancreatectomy [176]. Scharp et al [85] found that serum insulin and Kg values increased after intraportal transplantation in monkeys with mild diabetes induced by partial pancreatectomy and streptozotocin, but they did not report the long term fate or the actual course of diabetes in this model.…”

“…The collagenase digestion/Ficoll gradient separation technique has been used to isolate viable islets from mouse [97], dog [86], pig [98], monkey [85], and human pancreases [99]. In general, application to large animals has been difficult [100].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
