Overview
Normal Human Primary Intestinal Epithelial Cells Duodenem are human frozen primary cells from intestine used for barrier biology, transport, host-pathogen interactions, and tissue-specific epithelial response studies. These cells display adherent, epithelial growth characteristics.
Key elements and design rationale
- Biological source: Human (H. sapiens)
- Tissue origin: Intestine
- Growth properties: Adherent, epithelial
- Format: Frozen
- Seeding guidance: 60,000 cells/cm²
- Biosafety level: II
- Culture context: PriCoat™ ECM T25 Flasks (G999) or Applied Cell Extracellular Matrix (G422) are required for cell adhesion to the culture vessels. PriGrow X Series Medium (TM5526) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂.Note: cells cannot be subcultured.
Epithelial cells form polarized barriers that regulate transport, secretion, and defense at tissue interfaces. Their phenotype is shaped by cell polarity, junctional organization, and tissue-specific differentiation cues.
Research relevance and current trends
- Primary epithelial models are widely used to examine barrier integrity, cytokine responses, and transport processes under physiologic conditions.
- Researchers often combine epithelial cells with stromal or immune components to model tissue microenvironments more faithfully.
- Donor-matched or disease-context epithelial cells help capture inter-individual heterogeneity in response assays.
Common research applications
- Measure barrier integrity, junctional organization, and polarized responses in vitro.
- Evaluate cytokine, pathogen, or drug responses in tissue-relevant epithelial cultures.
- Use in co-culture or air-liquid interface-adjacent workflows when epithelial context matters.

- Seeding Density (cells/cm²): 60,000
Notes for experimental interpretation
- Primary cells can show donor-dependent and passage-dependent variation, so morphology, growth rate, and marker expression should be interpreted in the context of the specific lot and culture history.
- Attachment matrix, medium formulation, and gas conditions can materially influence phenotype maintenance and experimental readouts; use the recommended culture system where possible.
- Cryopreserved recovery conditions matter for viability and downstream behavior. We recommend using serum-free CryoGuard™ Freezing Media (TM078).
- Thaw cells quickly in a 37°C water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination.
- Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions.
- Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 600xg for 1 minute.
- Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask.
- Incubate the cells at the recommended conditions.
- Change media 24 hours after initial plating using pre-warmed complete media and every 48 hours, thereafter.
- Cells are expected to be greater than 50% confluent by day 5-7 after plating.
