Islets for Research: Nothing Is Perfect, but We Can Do Better

Area of Science:

• Endocrinology and Metabolism
• Transplantation Biology
• Diabetes Research

Background:

• Journals *Diabetes* and *Diabetologia* now require detailed reporting of human islet characteristics for studies.
• This policy aims to improve the reproducibility and comparability of islet research.
• The European Consortium for Islet Transplantation (ECIT) was invited to provide input.

Purpose of the Study:

• To outline the essential characteristics of human islets that should be reported in research publications.
• To offer recommendations from a leading consortium on islet research standards.
• To contribute to the ongoing dialogue regarding data transparency in diabetes and islet studies.

Main Methods:

• The European Consortium for Islet Transplantation reviewed the proposed reporting requirements.
• Consortium members discussed and consolidated essential islet quality and characterization parameters.
• Feedback was formulated based on expert consensus and practical considerations in islet research.

Main Results:

• The consortium identified key parameters for human islet characterization, including donor demographics, islet isolation procedures, and islet quality metrics.
• Specific recommendations were made regarding standardized terminology and data presentation.
• The feedback emphasizes the importance of comprehensive data for understanding islet function and dysfunction.

Conclusions:

• Standardized reporting of human islet characteristics is crucial for advancing diabetes research.
• The ECIT's contribution aims to facilitate the implementation of journal requirements.
• Adherence to these standards will enhance the reliability and impact of human islet studies.
