Primary Sprague-Dawley hepatocyte-derived 3D rat liver models delivering greater physiological relevance for investigative toxicology studies
- Leverage scaffold-free 3D microtissue models composed of primary rat hepatocytes and NPCs
- Predict drug-induced liver injury (DILI) in a 3D in vitro rat model that reflects in vivo species-specific toxicities (e.g., sensitivity to Acetaminophen)
- Perform mechanistic toxicity studies in an advanced model featuring intact hepatocyte function, bile salt excretion, and inflammatory-mediated toxicity pathways

Organotypic microtissue composition
3D InSight™ Rat Liver Microtissues are generated using cryopreserved primary rat hepatocytes and non-parenchymal cells (NPCs) in a ratio designed to reflect the organotypic cell composition of native rat liver. Hepatocytes are polarized and form functional bile-canaliculi. In addition, Kupffer cells are incorporated in the microtissue and display sensitivity to external stimuli, such as bacteria-derived lipopolysaccharide (LPS). The presence of stellate cells helps maintain hepatocyte functionality. No bioartificial scaffold materials are used in the microtissue production process. InSphero 3D InSight™ Rat Liver Microtissues are delivered in our spheroid-optimized assay plate, ready to use in experiments within hours of receipt in your lab.
Figure 1: Rat Liver Microtissues were stained for glycogen storage (Periodic Acid-Schiff, PAS), and presence of Kupffer cells (CD68 marker) and stellate cells (αSMA marker). Extensive storage of glycogen indicates high metabolic activity, CD68 staining shows incorporation of Kupffer cells in microtissues, and peripheral αSMA staining indicates the presence of stellate cells.
3D InSight™ Rat Liver Microtissues are an excellent alternative to traditional animal models for:
- Acute hepatotoxicity
- Species-specific toxicity testing
- Mechanistic toxicity testing
- Inflammation-mediated toxicity (idiosyncratic toxicity)
- Mitochondrial toxicity
- Oxidative stress
