Gastric Fundic Glands Isolation: A Method to Isolate Fundic Glands from Human Stomach Tissue

Samenvatting

Source: Teal, E. et al. Mouse- and Human-derived Primary Gastric Epithelial Monolayer Culture for the Study of Regeneration. J. Vis. Exp. (2018)

This video describes a method to isolate gastric epithelial cells from the human fundic tissue. The isolated epithelial cells can be used as an in vitro model to study their regulatory roles in gastric physiology and pathophysiology.

Protocol

All procedures involving human participants have been performed in compliance with the institutional, national and international guidelines for human welfare and have been reviewed by the local institutional review board.

1. Establishing Human-derived 3D Gastric Fundic Organoids

NOTE: To avoid contamination, perform protocol in its entirety within a sterile tissue culture hood. Human fundic tissue was collected from patients undergoing sleeve gastrectomy.

1. Collect the tissue from patients undergoing sleeve gastrectomy and place it in the ice-cold Ca²⁺/Mg
