Zebrafish pancreas as a model for development and disease

Area of Science:

• Endocrinology
• Developmental Biology
• Comparative Physiology

Background:

• The vertebrate pancreas has acinar tissue, a ductal system, and endocrine islets crucial for glucose homeostasis.
• Zebrafish share conserved metabolic regulation and organ development with mammals, making them a valuable model organism.
• Zebrafish offer advantages for islet cell development studies due to genetic manipulability, fecundity, and imaging accessibility.

Purpose of the Study:

• To review recent advancements in understanding endocrine cell development from duct-associated progenitors in zebrafish.
• To highlight new tools and technological approaches for studying beta cell physiology and glucose homeostasis in zebrafish.
• To describe emerging methods for creating zebrafish models of diabetes and related pathologies for therapeutic discovery.

Main Methods:

• Review of current literature on zebrafish islet cell development and function.
• Discussion of genetic manipulation and imaging techniques in zebrafish models.
• Exploration of novel methodologies for disease modeling and therapeutic screening.

Main Results:

• Recent progress in understanding duct-associated progenitor roles in endocrine cell formation.
• Advancements in tools for studying beta cell physiology and organism glucose homeostasis.
• Emerging zebrafish models for diabetes and related pathologies.

Conclusions:

• Zebrafish are a highly productive model for studying pancreatic islet development and glucose homeostasis.
• New tools and models in zebrafish facilitate the discovery of diabetes therapies and understanding disease pathology.
• The conserved nature of metabolic regulation supports the utility of zebrafish in endocrinology research.
