DIAGLYC TECHNOLOGY: artificial pancrea in closed loop

Applications

• rapid quality control of islets before transplantation, stem-cell differentiation protocols, stem-cell derived islets
• Real-time analysis of islet α-cells and β-cells, islets and their coupling, islets derived from iPSCs
• Organ-on-chip analysis to replace animal tests, to study drug effects, to study nutritional effects

Description

Islet cells plated on a Multi-Electrode Array (MEA) generate, in response to glucose or other nutrients and hormones, a flow of charges through ion channels near of the microelectrodes.

Two signals are observed: Slow potentials (SP) and action potentials (AP). They reflect single cell bahaviour (AP) and physiologically important intra-organ coupling (SP).

Electronic components provide on-line real-time processing of both types of signals, their direct analysis and scoring

Bénéfices

• Combination of biology and microelectronics offers a direct, easy and user-friendly approach to islet cell activity in physiological settings.

  It provides a versatile Organ-on-Chip approach.
