3D InSight™ Rat Islet Microtissues, Rat Islet Model | InSphero

A standardized in vitro rat islet model for translational diabetes studies and toxicity testing

InSphero 3D InSight™ Rat Islet Microtissues is currently in the final stages of product development and quality control testing. If you are interested in beta testing this product to help us further characterize the model and develop useful endpoints, please click on the Get Started button below or contact us.

  • Expand your GSIS assay window and improve sensitivity to insulin secretagogues with a long-lived, robust model persisting > 28 days in culture
  • Use an in vitro model that reflects native rat islet biology with homogeneous islet size and cellular composition
  • Increase efficiency by eliminating the need to hand pick islets, with microtissues available monthly and delivered assay-ready in a non-adherent Akura 96-well plate

Rat Islet Characterization Data

3D InSight™ Rat Islet Microtissues display stable viability, robust ß-cell function, and optimal incretin response for more than 28 days in culture. Within each microtissue, the endocrine cells adopt a ß-cell core and the non-β-cell mantle architecture similar to native rat pancreatic islets.

Uniform cytoarchitecture and functionality of rat islet microtissues enable simultaneous assessment of multiple endpoints (e.g. glucose-stimulated insulin secretion, total insulin, and ATP content) in a one-islet-per-well format. The standardized islet size provides more uniform compound penetration and simplifies the evaluation of changes in tissue size.
