Ex vivo culture of gastric and intestinal stem cells as organoids
Commonly used acronym: Gut organoids
Scope of the method
- Animal health
- Basic Research
- Translational - Applied Research
- In vitro - Ex vivo
- Animal derived cells / tissues / organs
- cellular differentiation
- gut organoids
- adult stem cells
- foetal progenitors
- intestinal stem cells
- gastric stem cells
- intestinal development
- Organoid biobank
- organoid preservation
- gut regeneration
- cellular differentiation
The tri-dimensional (3D) culture protocols allow isolation and culture of gastric epithelial antral and intestinal stem cells to efficiently generate organoids that recapitulate the mature pyloric and intestinal epithelium in vitro and foetal epithelial progenitors of these tissues growing as immature undifferentiated spheroids. The ex vivo culture approach is suitable to study gastric and intestinal function in homeostasis as well as in disease and developmental aspects of the gut.

Pros, cons & Future potential
The organoid technology offers the possibility to grow indefinitely foetal progenitors and adult stem cells in culture. The cryo-preserved organoid samples (as a biobank) can be regrown upon thawing, keeping their original properties. This substantially reduces the use of individual animals (pre and post-natally). For adult-derived organoid cultures, all epithelial cell lineages are spontaneously differentiated from adult stem cells, in a proportion similar to that observed in the tissue of origin in vivo. Cellular imaging, genomic, transcriptomic and proteomic studies can be easily performed on organoids as well as Drug screening assays and gene editing. A similar protocol is reported for generation of human biobanks from biopsies.
This 3R compliant method requires initial use of animals as starting material to generate the biobank. Moreover, this method only allows to investigate epithelium function and does not reproduce the complex in vivo environment of a tissue (which includes stromal mesenchymal, immune, nervous cells and systemic derived-factors). Therefore, this organoid technology cannot totally avoid animal use in research.
Epithelial-derived organoids can be co-cultured with additional cell types to recomplexify the in vivo environment.
Patient-derived organoids for personalized medicine.
