Overview

This article presents a protocol for establishing and culturing 3D gastric organoids derived from human and mouse tissues. It also details the transfer of these organoids to a 2D monolayer for use in regeneration studies.

Key Study Components

Area of Science

• Gastroenterology
• Cell Biology
• Regenerative Medicine

Background

• Understanding gastric epithelial cell regeneration is crucial for addressing gastric injuries.
• The study utilizes primary gastric cells to investigate cell migration and regeneration.
• This method can also be applied to other research areas, such as Helicobacter pylori infection.
• The procedure is demonstrated by a graduate student, Emma Teal.

Purpose of Study

• To generate a primary gastric monolayer for wound healing assays.
• To explore the mechanisms of gastric epithelial cell regeneration.
• To facilitate large-scale experiments using human-derived gastric organoids.

Methods Used

• Collection of prepared tissue in calcium magnesium-free DPBS.
• Establishment of 3D gastric organoids from human and mouse tissues.
• Transfer of organoids to a 2D monolayer.
• Application of a scratch-wound assay for regeneration studies.

Main Results

• The method allows for the study of cell migration in a controlled environment.
• Insights into gastric epithelial regeneration mechanisms were gained.
• Potential applications for studying other gastric conditions were identified.
• The protocol is suitable for both human and mouse-derived cells.

Conclusions

• This culture system is effective for studying gastric epithelial regeneration.
• The findings may contribute to understanding gastric injuries and healing processes.
• The technique has broader implications for various gastric research areas.
