Engineered tools to study endocrine dysfunction of pancreas.

Area of Science:

• Biomedical Engineering
• Endocrinology
• Tissue Engineering

Background:

• The pancreas regulates glucose and digestion; dysfunction causes diseases like diabetes mellitus.
• Murine models advance understanding but have limited clinical relevance due to genetic differences.
• Engineered in vitro models offer a promising alternative for studying pancreatic endocrine dysfunction.

Purpose of the Study:

• To review state-of-the-art engineered tools for studying pancreatic endocrine dysfunction.
• To highlight advancements in islet on a chip and live pancreatic slice technologies.
• To discuss the potential of combined strategies for next-generation pancreatic tissue modeling.

Main Methods:

• Review of current literature on engineered pancreatic models.
• Analysis of islet on a chip devices for controlled culture and noninvasive readouts.
• Evaluation of live pancreatic slices for recapitulating in vivo cellular interplay.

Main Results:

• Islet on a chip devices create physiomimetic niches for islet cultures.
• Live pancreatic slices offer comprehensive recapitulation of pancreatic cellular interactions.
• Challenges remain in long-term culture of live pancreatic slices, requiring controlled parameters.

Conclusions:

• Engineered tools like islet on a chip and live pancreatic slices are advancing pancreatic research.
• Combining islet-immune and slice on chip strategies can lead to improved pancreatic tissue models.
• These models hold promise for better understanding and treatment of endocrine pancreatic dysfunctions.
