Generation of a Bovine Primary Enteroid-Derived Two-Dimensional Monolayer Culture System for Applications in Translational Biomedical Research

Overview

This study presents a bovine primary cell 2D enteroid-derived culture system for investigating gastrointestinal tissue physiology and pathophysiology. The model allows for co-culture with relevant tissue cell types, enhancing translational research in gastrointestinal diseases.

Key Study Components

Area of Science

• Neuroscience
• Cell Biology
• Gastroenterology

Background

• Enteroids are a novel model for studying tissue interactions.
• Existing literature lacks reproducible protocols for novice researchers.
• The model aims to mirror in vivo conditions more closely.
• It addresses the complexity of host-pathogen interactions in cattle.

Purpose of Study

• To develop a detailed protocol for creating a robust cell culture model.
• To investigate immune factors influencing susceptibility to Cryptosporidium infection.
• To facilitate comparisons between adult cattle and calves.

Methods Used

• Creation of Transwell monolayers for co-culture with immune cells.
• Detailed step-by-step protocol for enteroid culture and dissociation.
• Measurement of transepithelial electrical resistance (TEER).
• Immunostaining to identify different cell lineages in enteroids.

Main Results

• Mature enteroids were observed by Day 7 with defined structures.
• TEER measurements indicated a stable epithelial barrier.
• Immunostaining confirmed the presence of enteroendocrine and Paneth cells.
• Confluent 2D monolayers were achieved in less than one week.

Conclusions

• The developed model is valuable for studying complex cattle diseases.
• It provides insights into tissue-pathogen interactions.
• The findings have potential translational implications for human health.
