Background
Three-dimensional organoid culture has moved from a specialist technique to a standard model system. Primary-tissue organoids retain the cell-type composition, polarity and architecture of the tissue they came from, which two-dimensional culture loses within days — and that gap is why regulators and funders are now pushing non-animal models for toxicology and disease work.
Gastric organoid culture depends on a different niche-factor balance from intestine, and the medium also has to hold the pit, isthmus and base cell populations of the gastric gland together rather than selecting for one.
This kit supplies that formulation as two components. Primary tissue goes in, organoids come out, and the composition is the same from lot to lot. Building an equivalent medium in-house from individual niche factors is expensive and hard to keep consistent between batches.
Description
Primary tissue to organoid. Biofargo Mouse Gastric Organoid Medium Kit is a serum-free, defined culture system for the establishment, expansion and long-term maintenance of mouse gastric organoids in three-dimensional matrix culture. It is supplied as a basal medium plus a concentrated culture additive, mixed before use.
The kit is designed for the full workflow rather than one step of it: organoid generation from freshly dissociated primary mouse gastric tissue, stable maintenance through passaging, and expansion of established lines. The defined, serum-free composition removes serum lot variation as a source of experimental drift, which matters when organoid cultures are carried for weeks.
For Research Use Only. Not for use in diagnostic or therapeutic procedures.

Features
Primary tissue to organoid in one kit — establishment, maintenance and expansion are covered by the same medium, so there is no switch between an establishment and a growth formulation partway through a culture.
Serum-free and defined — removes serum lot variation, which is the usual source of drift in organoid cultures carried for weeks.
Two-component format — basal medium plus concentrated additive; mix once and the complete medium is ready, with no multi-factor cocktail to assemble at the bench.
Gastric epithelial identity retained — organoids cultured in this medium retain tissue-specific marker expression rather than dedifferentiating, which is the practical advantage over two-dimensional culture.
Works with standard matrix embedding — compatible with routine basement-membrane matrix workflows and standard plate formats.
Species- and tissue-matched — formulated for mouse gastric tissue specifically, not a general-purpose organoid medium applied to every tissue.
Performance Data
Organoid formation and expansion from primary tissue
Following gastric glands isolation, cell collection and matrix embedding, organoid structures were observed during culture progression in Biofargo Mouse Gastric Organoid Medium Kit, and cultures reached a stage suitable for passaging and continued expansion.
Tissue-specific marker expression
Marker analysis of organoids cultured in this medium showed expression patterns associated with gastric epithelial identity, confirming that tissue character is retained through culture rather than lost to dedifferentiation. Markers examined included EpCAM and MUC5AC.
Applications
Helicobacter pylori and gastric infection studies: Gastric organoids are the standard in vitro model for H. pylori colonisation, epithelial injury and the inflammatory response to it.
Gastric cancer initiation research: Study the epithelial changes that precede gastric carcinogenesis in a tissue-derived model; for established tumour organoids, see the human gastric cancer organoid medium.
Gastric epithelial biology: Mucous cell differentiation, parietal and chief cell lineages, and gastric stem cell behaviour in a self-organising culture.
Drug and compound response: Assess gastric epithelial toxicity and compound effects in a three-dimensional model.
Disease modelling from genetic models: Generate organoids from knockout or transgenic animals to study gastric pathway biology.
Organoid expansion and biobanking: Maintain and expand established lines for repeated downstream assays from a single tissue harvest.
Organoid models complement, rather than replace, in vivo work. Findings should be confirmed in the model system appropriate to the research question.
Kit Components
| Component | Volume | Storage |
| Mouse Gastric Organoid Basal Medium | 96 mL | 2–8 °C |
| Mouse Gastric Organoid Culture Additive | 4 mL | −20 °C |
Storage & Shipping
Shipped with cold packs.
Store the basal medium at 2–8 °C and the culture additive at −20 °C.
Mix the additive into the basal medium to prepare complete medium. Aliquot the additive to avoid repeated freeze-thaw cycles.
Prepare only the volume of complete medium needed for near-term use and keep it at 2–8 °C.
Protocol Overview
Collect mouse gastric tissue and wash in PBS.
Dissociate the tissue and prepare gastric glands or tissue-derived cells.
Filter and collect cells after digestion.
Embed the cells in basement-membrane matrix for three-dimensional culture.
Prepare complete medium by mixing the culture additive into the basal medium, and overlay the matrix.
Culture at 37 °C, 5% CO2, replacing the complete medium on the documented schedule.
Passage when organoids have reached a size suitable for dissociation and re-embedding.
Frequently Asked Questions (FAQs)
Common questions about Biofargo Mouse Gastric Organoid Medium Kit.
What is this kit used for?
It is a serum-free, defined medium kit for establishing, maintaining and expanding mouse gastric organoids from primary mouse gastric tissue in three-dimensional matrix culture.
Does it start from primary tissue or from stem cells?
Primary tissue. Organoids are established from freshly dissociated primary mouse gastric tissue, not from pluripotent stem cells. Tissue dissociation, filtration and matrix embedding precede the first medium change.
Is the medium serum-free?
Yes. The formulation is serum-free and defined, which removes serum lot variation as a source of experimental drift across long cultures.
What is in the kit, and how is complete medium prepared?
The kit contains 96 mL of basal medium and 4 mL of concentrated culture additive. Mix the additive into the basal medium to give 100 mL of complete medium. Prepare only what is needed in the near term and keep it at 2–8 °C.
Can the medium support expansion and passaging, not just establishment?
Yes. The same medium covers establishment, long-term maintenance and expansion, so there is no change of formulation partway through a culture.
What matrix and culture conditions are required?
Cells are embedded in basement-membrane matrix and cultured at 37 °C with 5% CO2. The matrix is not included; a growth-factor-reduced, phenol red-free basement membrane matrix is available separately.
Do the organoids retain tissue identity?
Marker analysis of organoids cultured in this medium shows expression patterns associated with gastric epithelial identity. This is the practical advantage over two-dimensional culture, where tissue-specific function is lost within days.
Can organoids be cryopreserved and recovered?
Yes. Established lines can be banked with a protein-free organoid cryopreservation solution and recovered into this medium, so one tissue harvest supports repeated experiments over time.
How is it stored and shipped?
Shipped with cold packs. Store the basal medium at 2–8 °C and the culture additive at −20 °C.
Can it be used for clinical or diagnostic purposes?
No. This product is for research use only and is not intended for human, diagnostic or therapeutic use.
