Liver Fibrosis

Cell Inoculation

Bile Duct Cannulation

Liver Fibrosis

A quantitative evaluation of a therapeutic’s ability to halt or reverse the progression of hepatic fibrogenesis is a critical hurdle for any anti-fibrotic program. BioLegacy provides definitive assessments using robust, extensively validated, chemically-induced liver fibrosis models in mice and rats. Our expertise in these platforms allows for a clear characterization of your compound’s impact on hepatocyte injury, stellate cell activation, and extracellular matrix deposition, delivering the pivotal histopathological and biochemical data required to confirm efficacy.

  • CCl₄-Induced Fibrosis: The gold-standard, highly reproducible model of centrilobular liver injury and fibrosis, ideal for evaluating the efficacy of hepatoprotective and anti-fibrotic agents.
  • DMN-Induced Fibrosis: A model utilizing dimethylnitrosamine (DMN) to induce a distinct pattern of fibrosis that closely mimics the histopathological features of human cirrhosis.

Cell Inoculation

Modeling specific liver pathologies, from metastatic disease to humanized liver systems, requires the precise delivery of cells directly to the target organ. BioLegacy’s advanced microsurgical platform is engineered for this purpose, providing expert, image-guided cell inoculation directly into the liver parenchyma or portal circulation. This specialized capability allows for the creation of robust, highly translatable models of hepatic disease, enabling a definitive assessment of your therapeutic’s efficacy in a clinically relevant context.

  • Intrahepatic & Intrasplenic Injection: Direct delivery of cells to the liver or via the portal vein to model liver metastasis.
  • Hepatocellular Carcinoma (HCC) Models: Orthotopic implantation of HCC cells to study primary liver cancer in its native microenvironment.
  • Cell Therapy & Regenerative Medicine: Assess the safety, engraftment, and efficacy of hepatocyte transplantation or other liver-directed cell therapies.
  • Humanized Liver Models: Study human-specific metabolism or viral pathogens via engraftment of human hepatocytes.

Bile Duct Cannulation

A definitive understanding of a compound’s excretory pathways and potential for enterohepatic circulation is a critical component of any ADME package. At BioLegacy, our bile duct cannulation (BDC) platform in rats and dogs provides this essential, quantitative data with unparalleled precision. Cannulation by our expert microsurgeons allow for the direct, continuous collection of bile, enabling a definitive mass balance assessment and clear characterization of your therapeutic’s primary routes of elimination and metabolites.

  • Definitive Biliary Excretion Data: The gold-standard model for directly quantifying the extent of a compound's biliary clearance.
  • Enterohepatic Circulation Assessment: Precisely measure the reabsorption of a compound or its metabolites from the intestine.
  • Metabolite Profiling in Bile: Identify and quantify of metabolites excreted via the biliary route.
  • Integrated PK & Mass Balance Studies: Provides a complete picture of a compound's absorption, distribution, metabolism, and excretion (ADME).
  • Expert Microsurgical Cannulation: Highly experienced surgical team led by world-renowned surgeon.
