Immortalized Murine Intestinal Epithelial Cells

CI-muADINTESTI are immortalized murine adult intestinal epithelial cells. Intestinal epithelial cells form the single layer of epithelium that lines both, the small and large intestine. They play vital roles in digestion, nutrient absorption, and barrier function within the digestive system. Three main cell types make up the intestinal epithelium, the absorptive epithelial cells (enterocytes), goblet cells and Paneth cells.


  • Organoid formation in 3D culture conditions
  • Expression of intestinal epithelial markers including ZO-1, E-cadherin, Muc2 and Lgr5
  • Barrier and tight junction formation on cell culture inserts


We offer two different murine intestinal cell lines muADINTESTI and muINTEPI (INS-CI-1007). We generally recommend using muADINTESTI cells, muINTEPI is a legacy product and only available upon request. See the FAQ for more information.

Product FAQ

CI-muINTEPI and CI-muADINTESTI are both murine intestinal epithelial cell lines developed and distributed by us, but they originate from different source tissue, stages of tissue development and have distinct characteristics.

CI-muINTEPI cells were generated from murine fetal small intestinal tissue (Schwerk et al., 2013). They express typical epithelial markers and show polarized growth. CI-muINTEPI cells have been used in a wide range of infection and immunity studies, e.g., interferon signalling, Salmonella infection and Cryptosporidium infection.

CI-muADINTESTI are immortalized cells derived from murine adult intestinal tissue. Isolated primary cells were cultured as intestinal organoids before immortalization to maintain optimal functionality. muADINTESTI express typical epithelial markers and grow polarized. They form a barrier of approx. 2000 to 4000 Ohm×cm2 (TEER) already on day 5 after seeding on membrane cell culture inserts.

When selecting a cell culture model, consider the type of assay and experiment you would like to perform. When setting up a new model system, we recommend using CI-muADINTESTI cells for most applications. Overall, we found them to be more robust and more functional than CI-muINTEPI cells. However, if you would like to build upon already published results, which were generated using CI-muINTEPI cells, consider using them instead. We are happy to support you anytime – please get in touch with us!

For the best performance of this cell line, we advise using our Medium and Coating Solutions specified in the product sheet. These have been specially optimized for these cells. While it may be possible to adapt the cells to a different medium, we cannot assure their optimal performance outside our recommended Medium and Coating Solution. To validate any new culturing conditions, we suggest conducting comparative tests with our recommended protocols to confirm the cells‘ expected behavior.

All our cell lines were immortalized using our custom library of immortalization genes. This library contains a combination of specifically selected immortalization genes encoded in lentiviruses. For a detailed description of our immortalization technology refer to Lipps et al. Nat comm vol. 9,1 994. 2018.

Firstly, it is worth mentioning that passage number is not always a reliable indicator of cell ageing due to its dependence on variables like seeding densities and split ratios. However, they can provide useful guidance in routine cell culture.

Our cell lines are truly immortalized, allowing for indefinite culturing. Nonetheless, we advise caution beyond passage 50. While more stable than typical cancer cell lines, our cells can still undergo changes with prolonged culture. We recommend periodically assessing cell performance after passage 50.

Typically, our immortalized cells are provided at passages 5 to 15. To avoid running out of material, we suggest banking cells immediately after initial expansion. This strategy ensures you always have sufficient cells for your research.

Should there be any concerns about depleting your cell stock, you have the option to order a new vial of cells as a replacement for a handling fee.

This cell line is BSL 1 according to German legislation. However, persons working with such cell lines and their employers are required to familiarize themselves with the national regulations and safety precautions, as they may differ. Our provided biosafety classification does not provide any exemption from this responsibility. 

Yes, you can use our immortalized cell lines for commercial purposes with the appropriate license. We provide an initial evaluation phase for our cell lines at a flat fee of €3,500 for a 3-month license, or €5,000 for a 6-month license. During this period, use of the cells is limited to internal research, development, and validation.

For commercial use beyond the evaluation phase, we offer various licensing options, such as:

  • Internal research and development
  • CRO license (providing research services to third parties)
  • Assay license


Please contact us to find the licensing option that best fits your needs.

Our immortalized cell lines are fully characterized and can be expanded indefinitely, making them a one-time purchase for perpetual use. This differs from primary cells, which are consumables you would need to repurchase. The licensing model not only respects the perpetual use value but also allows us to adjust fees based on your specific use case. Consider two scenarios: Customer A wants the cells for a single assay at one site for a limited time, while Customer B plans to use them globally across multiple sites for drug discovery and additionally transfer them to a CRO. Charging both customers the same one-time fee would not account for the vastly different use cases. That’s why our license fees are tailored to fit your unique needs.
