Generation and Quantitative Imaging of Enteroid Monolayers.

Area of Science:

• Gastroenterology
• Cell Biology
• Biotechnology

Background:

• The intestinal epithelium is vital for digestion, nutrient absorption, and host-microbe-immune interactions.
• Maintaining intestinal epithelial homeostasis is crucial for preventing diseases like inflammatory bowel disease and cancer.
• 3D intestinal organoids have improved understanding but have limitations in high-throughput and single-cell analysis.

Purpose of the Study:

• To present experimental and computational methods for generating and analyzing 2D enteroid monolayers.
• To provide a high-throughput platform for studying intestinal epithelial biology.
• To enable detailed single-cell analysis of epithelial homeostasis and disease.

Main Methods:

• Generation of enteroid monolayers from fresh, frozen intestinal crypts, or 3D organoids.
• Culture of enteroid monolayers in microtiter plates for high-throughput screening.
• Computational analysis of immunofluorescence images to identify cell types and nuclei for single-cell measurements.

Main Results:

• Enteroid monolayers recapitulate key features of the in vivo intestinal epithelium, including tissue renewal and cell diversity.
• The 2D format facilitates fluorescent microscopy and quantitative single-cell analysis.
• Methods are described for deriving enteroid monolayers from various sources, including patient samples.

Conclusions:

• The developed 2D enteroid monolayer system offers a powerful, high-throughput tool for studying intestinal epithelial homeostasis.
• These methods enable precise, single-cell level investigations into the mechanisms of intestinal health and disease.
• The versatility of the system supports genetic modification and biobanking for future research.
