Summary
A novel biofabrication technique creates functional intestine models with realistic crypt/villus structures. This biomimetic model accurately replicates intestinal barrier functions and disease states for research.
Area of Science:
- Biomaterials Science
- Tissue Engineering
- Gastroenterology
Background:
- Replicating the complex crypt/villus topography of the intestine is crucial for developing accurate in vitro models.
- Existing methods face challenges in recreating the intricate microarchitecture of the intestinal lining.
Purpose of the Study:
- To develop an inverse molding biofabrication technique for creating functional intestinal models with native-like crypt/villus structures.
- To establish a biomimetic intestinal model for studying barrier function and disease states.
Main Methods:
- Utilized digital light processing (DLP) 3D printing to create a sacrificial hydrogel mold (SHM) with negative crypt/villus features.
- Employed decellularized small intestine submucosa-norbornene (dSIS-NB) solution cast over the SHM, followed by photopolymerization.
- Achieved SHM dissolution to yield dSIS-NB hydrogels with positive crypt/villus structures.
Main Results:
- Intestinal epithelial cells formed confluent monolayers with correct polarity on the dSIS-NB matrices within 3 days.
- The model demonstrated selective and drug-responsive barrier functions, confirmed by transepithelial electrical resistance (TEER) and transport studies.
- Successfully created an intestinal disease model incorporating both healthy and diseased (flattened) epithelial regions.
Conclusions:
- The inverse molding technique effectively fabricates biomimetic intestinal models with native-like crypt/villus structures.
- This advanced model accurately recapitulates intestinal barrier properties and enables the study of disease pathophysiology.
- The developed biofabrication method offers a promising platform for creating complex tissue models for drug screening and regenerative medicine.
