Highlights

This review highlights Organ-Chips as a more human-relevant preclinical platform that recreates key aspects of organ physiology—including tissue-tissue interfaces, dynamic fluid flow, mechanical forces, and immune interactions—to improve prediction of human drug responses. Unlike conventional cell cultures or animal models, Organ-Chips enable therapeutics to be evaluated using clinically relevant dosing routes and pharmacokinetic profiles, supporting more accurate assessment of efficacy, toxicity, and mechanisms of resistance. The authors also emphasize that combining Organ-Chips with high-throughput screening, functional genomics, and artificial intelligence could accelerate target identification and drug discovery while helping reduce the high rate of clinical trial failures. Although challenges remain around standardization and scalability, the review concludes that Organ-Chips are poised to become an increasingly important tool for drug development and regulatory safety assessment.

Synopsis

Organ-on-a-Chip technology is emerging as a powerful New Approach Methodology (NAM) for drug development, driven by the need for more human-relevant and scalable experimental models. As these systems move toward broader adoption, a key challenge remains: generating consistent, interpretable data that supports confident experimental and translational decision-making.

This webinar examines how imaging and AI-driven analysis workflows enable Organ-Chip studies to scale from innovation to routine application. Speakers begin with an overview of Organ-on-a-Chip technology and its role in addressing translational gaps in drug discovery, highlighting how Liver-Chips are being evaluated in collaboration with regulatory agencies for better prediction of drug-induced liver injury.

The session then explores how the newly released AVA™ Emulation System enables scalable Organ-Chip experimentation through an integrated system for incubation, microfluidic delivery, and routine imaging. Paired with AI-driven analysis, brightfield image data can be used to automate quality control by monitoring chip health, morphology, and assay performance over time across large studies.

To complete the workflow, post-study high-resolution imaging is applied to evaluate more complex biological markers, including toxicology-relevant endpoints and drug uptake. These datasets are paired with advanced analysis techniques that translate imaging data into quantitative, biologically meaningful insights.

Attendees will gain a practical understanding of how unified imaging and analysis strategies—spanning routine QC through advanced interrogation—support scalability, reproducibility, and alignment with evolving regulatory expectations for Organ-Chips and other NAM-based drug development.

Abstract

Read this publication to learn how researchers built a prototype Chip-A1 Accessible Chip to address many of the challenges associated with the Organ-on-a-Chip technology, including incorporation of a tissue-specific extracellular matrix gel seeded with primary stromal cells, to reproducing the architectural complexity of tissues by micropatterning the gel, to extracting the gel for H&E staining.

Organ Model: Lung (Alveolus) & Skin

Application: Model Development

Abstract: Nearly all human organs are lined with epithelial tissues, comprising one or multiple layers of tightly connected cells organized into three-dimensional (3D) structures. One of the main functions of epithelia is the formation of barriers that protect the underlining tissues against physical and chemical insults and infectious agents. In addition, epithelia mediate the transport of nutrients, hormones, and other signaling molecules, often creating biochemical gradients that guide cell positioning and compartmentalization within the organ. Owing to their central role in determining organ-structure and function, epithelia are important therapeutic targets for many human diseases that are not always captured by animal models. Besides the obvious species-to-species differences, conducting research studies on barrier function and transport properties of epithelia in animals is further compounded by the difficulty of accessing these tissues in a living system. While two-dimensional (2D) human cell cultures are useful for answering basic scientific questions, they often yield poor in vivo predictions. To overcome these limitations, in the last decade, a plethora of micro-engineered biomimetic platforms, known as organs-on-a-chip, have emerged as a promising alternative to traditional in vitro and animal testing. Here, we describe an Open-Top Organ-Chip (or Open-Top Chip), a platform designed for modeling organ-specific epithelial tissues, including skin, lungs, and the intestines. This chip offers new opportunities for reconstituting the multicellular architecture and function of epithelial tissues, including the capability to recreate a 3D stromal component by incorporating tissue-specific fibroblasts and endothelial cells within a mechanically active system. This Open-Top Chip provides an unprecedented tool for studying epithelial/mesenchymal and vascular interactions at multiple scales of resolution, from single cells to multi-layer tissue constructs, thus allowing molecular dissection of the intercellular crosstalk of epithelialized organs in health and disease.
