Area of Science:

• Biotechnology
• Cell Biology
• Gastroenterology

Background:

• 3D cell cultures, including organoids, are vital tools in biomedical research.
• Pancreatic organoids are crucial for modeling diseases like pancreatitis and studying exocrine functions.

Purpose of the Study:

• To present protocols for generating and manipulating pancreatic organoids with controlled polarity.
• To facilitate the study of human pancreatic epithelial secretion using advanced 3D models.
• To provide a cost analysis for implementing these advanced culture techniques.

Main Methods:

• Establishment and maintenance of pancreatic patient-derived organoids (PDOs).
• Cryopreservation and thawing techniques for pancreatic PDOs.
• Protocols for inducing apical-to-basal polarity switching in pancreatic organoids.

Main Results:

• Detailed protocols for pancreatic PDO culture and polarity manipulation are provided.
• A comprehensive cost breakdown for implementing these advanced methods is included.
• The study encourages the adoption of human primary cells over rodent models.

Conclusions:

• Advanced pancreatic organoid culture methods, including polarity switching, enhance human epithelial secretion studies.
• These protocols and cost analyses support the transition to human-based research models.
• The findings align with efforts to accelerate clinical translation of scientific discoveries.
