Their strengths?
➡️ High physiological relevance
➡️ Cross-species compatibility
➡️ Reduced animal usage
➡️ Compatible with imaging, omics & functional assays

But success hinges on one thing: precise vibratome slicing.

Precision-Cut Liver Slices preserve the liver’s native multicellular architecture—including hepatocytes, Kupffer cells, stellate cells & endothelial cells.

This makes them ideal for studying:
➡️ Hepatotoxicology
➡️ Liver fibrosis
➡️ Metabolic diseases
➡️ Pharmacokinetics
