Background:

Pancreatic dysfunction in diabetes is increasingly linked to interactions with other organs, particularly the liver.
Understanding multi-organ crosstalk is crucial for developing effective diabetes therapies.
Existing models may not fully capture the complex interplay between pancreatic and hepatic cells.

Purpose of the Study:

To engineer a co-culture system that mimics pancreas-liver interactions.
To create a platform for studying multi-organ crosstalk in diabetes.
To facilitate mechanistic studies and therapeutic testing.

Main Methods:

Development of a co-axial flow-focusing microfluidic device.
Fabrication of multi-compartment hydrogel microcapsules using poly(ethylene glycol) (PEG).
Encapsulation of pancreatic beta-cells and hepatic cells into separate compartments within each microcapsule.

Main Results:

Encapsulated cells self-assembled into pancreatic and hepatic spheroids.
Co-cultures demonstrated enhanced pancreatic and hepatic function compared to single-cell type cultures.
The microcapsule system supported cell viability and function over time.

Conclusions:

Multi-compartment microcapsules represent a novel microphysiological system.
This system effectively models pancreas-liver crosstalk.
The platform shows promise for accelerating mechanism discovery and drug development in diabetes research.
