Gastrointestinal Cells TRIZ Cases
- Nanoantibody VHH Domain for Norovirus Inhibition
A nanoantibody binds norovirus particles to block intestinal cell infection.
- Lgr5+ Stem Cell Expansion Using CHIR99021 and Valproic Acid
Combining CHIR99021 with valproic acid replaces Paneth cell contact to expand Lgr5+ stem cells while maintaining self-renewal fidelity.
- IBD Stem Cell Culture System for Disease Modification
Isolates intestinal stem cells via extraction and intermediary support to resolve the trade-off between symptom control and addressing root cause mechanisms.
- Esophageal Organoid Medium Composition for High-Passage Success
Adjusted growth factor concentrations in the culture medium increase passaging success rates for patient-derived esophageal organoids.
- Biomaterial-Encapsulated Cell Mass Fabrication for Drug Screening
A high-throughput method fabricates biomaterial-encapsulated cell masses using photo-crosslinkable hydrogels and automated imaging analysis.
- Double-Layer Hydrogel Wrinkle Structure via Compressive Strain
Segmented hydrogel layers resolve manufacturing precision limits by replicating natural epithelial tissue deformations under specific compressive strains.
- Patterned Cell Culture Substrate for Intestinal Epithelial Differentiation
A patterned cell culture substrate directs stem cell adhesion and differentiation into small intestinal epithelial cells.
- Intestinal Epithelium Culture via Air-Liquid Interface
A gel substrate with an air-liquid interface enables continuous growth of mammalian intestinal cells for extended periods.
- Recombinant Adenovirus p53-Selective Replication
Recombinant adenoviruses exploit defective p53 pathways to selectively replicate in cancer cells while sparing normal tissue.
