Implication

Comparative imaging study reveals distinct cell distribution and compositional heterogeneity in human pancreatic islets, highlighting structural divergence from rodent models.

Key Points

To examine the structural organization and cell type composition of isolated human pancreatic islets in comparison with mouse and non-human primate islets.
Analyzed isolated human pancreatic islets from six separate isolations across three isolation centers using confocal laser scanning microscopy.
Calculated alpha-, beta-, and delta-cell volumes and distributions using 3D image analysis software.
Compared human islet architecture to isolated mouse islets, isolated non-human primate islets, and intact human pancreatic tissue sections.
Murine islets displayed a classic core-mantle structure with alpha and delta cells restricted to the periphery, whereas human islets demonstrated alpha, beta, and delta cells dispersed throughout the entire islet.
Non-human primate islets showed an intermingled cytoarchitecture similar to human islets, whereas human islets displayed marked inter-islet heterogeneity in cell proportions and volumes compared to the uniform composition of rodent islets.
