Artificial Intelligence in Digital Pathology: Quantification of Fibrosis in Human 3D NASH Model
Non-Alcoholic Steatohepatitis (NASH) is a serious and complicated disease with strong associations to other metabolic condition such as diabetes and obesity. NASH begins with asymptomatic steatosis and can progress with subsequent liver inflammation and fibrosis leading to cirrhosis, liver failure, liver transplant and even hepatocellular carcinoma (HCC). Although there is an alarming percentage of the adult world population with at least early stages of NASH, there has not yet been a drug approved for this complex disease, except the PPARα/γ agonist saroglitazar from Zydus. The preclinical animal and cell culture models used to date have not accurately predicted drug efficacy effects once they reach the clinic, particularly with the fibrosis-associated endpoints.
In this webinar, InSphero Scientific Ambassador Dr. Sue Grepper focused on a novel human 3D NASH model, consisting of 4 different liver cell types relevant to this disease development. New findings were shared relating to compound modalities other than classic small molecules, as well as new quantitative fibrotic measurements achievable with this model. PharmaNest CEO Dr. Mathieu Petitjean presented the FibroNest™ Digital Pathology AI platform for innovative phenotypic quantification of fibrosis based on histology liver slices of 3D NASH model using over 400 parameters relating to the fibrosis content, morphometry and architectural histological phenotypes. The fibrosis quantification in the 3D NASH model is extremely useful for better understanding the mechanism of action of anti-fibrotic compounds on collagen deposition. The use of the FibroNest AI platforms allows to discover translational insights through similar quantifications and validations as performed for rodents and humans. This complex disease model and histological assay could be used as a translational drug discovery tool for prediction of efficacy and potency of anti-fibrotic compounds of in the clinic.
In this webinar, we covered:
• Modeling of key NASH hallmarks: steatosis, inflammation and fibrosis
• Scalable endpoints, including clinical biomarkers for drug efficacy testing
• Live demonstration of FibroNest™ Digital Pathology AI platform for phenotypic quantification of fibrosis based on histology tissue slices
• Efficacy testing of various modalities NASH compounds such as antibodies and small molecules
In vitro spheroid models are fast becoming the de facto standard for drug discovery applications, largely due to their human-like physiological and morphological characteristics, tissue-like cellular complexity, and long culture lifespan, which enables longitudinal studies that better reflect patient treatment plans in the clinic. High content imaging and analysis (HCA) of 3D spheroid models can provide valuable information to help researchers untangle disease pathophysiology and assess novel therapies more effectively. Making the move from simple monolayer 2D cell models to dense 3D spheroids in HCI applications, however, requires 3D-optimized protocols, instrumentation, and resources.
In this webinar, we will discuss considerations for high content imaging and analysis of 3D spheroid disease models for drug discovery, share lessons we learned while in setting up and conducting proof-of-concept studies designed to test the full potential for high-resolution image-based analysis of 3D spheroid models and provide a working checklist for researchers and core services groups planning to exploit these technologies in their work.
You will learn:
- Core advantages of 3D models and 3D in vitro technology engineered for drug discovery applications, and the range of rich, physiologically relevant data you can extract from 3D disease models using HCA methods.

How to Evaluate Preclinical and Clinical DILI
A Strategic Approach for Applying 3D Models and Methodologies to Bridge the Gap between In Vitro and In Vivo
Despite ongoing investments in research, advances in technology, and improved knowledge and understanding of human disease, approximately 90% of new drugs entering clinical trials fail, largely due to safety issues in clinical phases or drug efficacy issues in patients. Why? Because preclinical approaches that use in vivo animal models and in vitro cell models for discovery and development still do not reliably translate to patients.
In this webinar, InSphero CSO Prof. Armin Wolf will discuss how the research community gets “lost in translation” and share his strategy for bridging the divide between preclinical and clinical research to bring safe, effective drugs to market – and to patients in need of new therapeutics. Armin will introduce a “causality assay” framework for evaluating drug-induced liver injury (DILI) with novel 3D in vitro models and methodologies, and explain how multicellular 3D human liver spheroids can be used for investigating a broad range of experimental conditions using a variety of analytical methods, from liver enzyme markers and histological techniques to the latest ‘omics technologies. He'll also walk you through several examples of successful applications of causality assays for the deconvolution of major DILI mechanisms – and offer his vision for the future of 3D in vitro tools for translational liver toxicology – and beyond.
You will learn:
- The challenges of drug discovery and translation (from in vitro and in vivo models to patients)
- The current gold standard: ATP-based DILI hazard identification
- Stepping beyond ATP: from hazard identification to risk assessment
- Impact of 3D spheroid models in drug development
- Future challenges and opportunities
Modeling NAFLD: from Steatosis to NASH and Fibrosis
