Islet Core

The Islet Core provides comprehensive in vivo, ex vivo, and in vitro analysis of pancreatic function and islet structure. The Core services enhance whole body metabolic characterization given the interrelatedness of insulin action and insulin secretion, while altered islet function and mass play an important role in the onset of diabetes phenotypes (hyperglycemia). The Core also bridges an important scientific gap caused by difficult accessibility of islets and paucity of islet material by offering sophisticated islet phenotyping tools and expertise. The Core phenotyping services include:

  • Mouse pancreas preparation for histological experiments
  • Surgical isolation of mouse islets
  • Measurement of b-cell mass, proliferation, and cell death
  • Islet structural analysis
  • Ex vivo islet functional analysis using perifusion system for insulin secretion and insulin content
  • In vitro molecular analysis using cultured islets
  • Structural and functional analysis of human islets in coordination with Humanized Mouse Cell Transplantation and Assessment Core.
