Area of Science:

Endocrinology
Cell Biology
Transplantation Science

Background:

Islet purification is critical for transplantation and research.
Density gradient separation alone yields low purity islets due to residual exocrine cells.
Improved islet purification methods are needed to enhance transplant success.

Purpose of the Study:

To develop a novel islet purification process.
To improve islet purity beyond standard density gradient methods.
To evaluate the impact of a new process on islet viability and function.

Main Methods:

A two-step purification process was developed: hypertonic-hypotonic treatment followed by density gradient centrifugation.
The Plackett-Burman method identified key factors influencing purification.
Islet purity, viability, and insulin secretion were assessed.

Main Results:

Hypertonic solution concentration and incubation time significantly impacted islet purity.
The modified purification process achieved significantly higher islet purity (97%) compared to density gradient alone (87.23%).
Islet viability and insulin secretion capacity were preserved.

Conclusions:

The novel purification process effectively enhances islet purity.
The method does not compromise essential islet viability or function.
This technique offers a promising advancement for islet isolation.
