Engineered islets, called Kanslets, overcome diffusion barriers and improve survival for diabetes research and therapy. These custom-designed, small islets show higher viability and restore normal blood glucose in diabetic rats.

Area of Science:

  • Biotechnology
  • Cell Biology
  • Regenerative Medicine

Background:

  • Isolated islets are crucial for diabetes research and therapies but face limitations due to diffusion barriers and core cell death.
  • Native islets larger than 100 μm exhibit poor oxygen and glucose diffusion, leading to reduced cell viability and function.

Purpose of the Study:

  • To engineer optimal islets with improved diffusion, viability, and function for diabetes research and transplantation.
  • To develop a novel micromold-based approach for creating uniform, small, and functional engineered islets.

Main Methods:

  • Empirical modeling to understand islet diffusion limitations.
  • Dispersing native islets into single cells and reaggregating them in custom conical micromolds over several days.
  • Characterizing engineered islets (Kanslets) for size, cellular composition, insulin production, microvilli, viability, and glucose diffusion.

Main Results:

  • Engineered islets (Kanslets) were consistently under 100 μm, mimicking native islet composition and function, including insulin production and microvilli.
  • Kanslets demonstrated statistically higher viability and enhanced glucose diffusion compared to native islets.
  • Transplantation of engineered islets into diabetic rats rapidly normalized blood glucose levels within 48 hours.

Conclusions:

  • Engineered islets (Kanslets) offer a viable alternative to native islets for research, drug discovery, and clinical applications.
  • The micromold-based reaggregation technique provides a scalable method for producing optimized three-dimensional tissue.
  • This approach has significant implications for advancing tissue engineering and therapeutic strategies for diabetes.
