Human In Vitro Small And Large Intestinal Tissue Models
Accurate biological screening based on real human intestinal tissue, with a standardized workflow for reliable and reproducible data, RepliGut® represents 
the next generation for in vitro testing with faster actionable data.
Human in vitro small and large intestinal tissue models exhibiting polarized monolayers encompassing cell types reflecting in vivo biology. This platform is suitable for studying many aspects of drug disposition including toxicity, metabolism, drug absorption, and efficacy.
Intestinal Barrier Function
Integrity of the intestinal epithelium is crucial for the normal functioning of the lower GI tract. RepliGut® maintains barrier integrity with high TEER values. Compounds can be assessed for the potential to disrupt barrier function or the barrier can be compromised with cytokines and the reestablishment of barrier function quantified.
Inflammatory Response
Inflammation of the GI tract is the main hallmark of Inflammatory Bowel Disease. The RepliGut® system is comprised of polarized intestinal cells grown on transwells. Dosing with compounds can be in the luminal or basolateral compartments and sampling for the release of inflammatory mediators can be quantified in either compartment as well.
GI Toxicity
GI toxicities are among the most common adverse events during Phase 1 clinical trials. RepliGut® recapitulates intestinal epithelium and can be used to screen compounds for drug-induced GI toxicity early in the drug development process.
Intestinal Drug Disposition
RepliGut® can be used to measure the uptake or efflux of compounds in a manner similar to Caco-2 cells. RepliGut® is superior to Caco-2 cells because the cells are not transformed, and studies can be conducted with cells derived from the different regions of the small intestine and colon. More than one donor can be tested.
