"What Is Organ-on-a-Chip?" — HSE University's Laboratory of Molecular Physiology Releases Popular Science Video with the LessON Project
The Laboratory of Molecular Physiology at the HSE University Faculty of Biology and Biotechnology, in collaboration with the HSE University LessON project, has released a popular science video lecture entitled "What Is Organ-on-a-Chip?" In the video, laboratory head Evgeny N. Knyazev explains how microfluidic devices that mimic human organ function are transforming modern biomedical research.
The Laboratory of Molecular Physiology at the HSE University Faculty of Biology and Biotechnology is pleased to announce the release of a new popular science video, "LessON: What Is Organ-on-a-Chip?", produced jointly with the HSE University LessON educational project. The video is available at: https://vkvideo.ru/video-25205856_456240916. The lecture was delivered by Evgeny N. Knyazev, Candidate of Medical Sciences, Associate Professor at the IBC RAS–HSE joint department, and Head of the Laboratory of Molecular Physiology at HSE University.
The video introduces viewers to organ-on-a-chip technology — one of the most promising frontiers in contemporary biomedicine. Organs-on-a-chip are microfluidic devices roughly the size of a USB drive that combine advances in microfluidics, tissue engineering, cell biology, and biomaterials. Their microchannels and chambers are populated with living human cells, while a flowing nutrient medium mimics blood circulation. These devices can reproduce the three-dimensional architecture of living tissue, intercellular interactions, and dynamic physiological processes such as breathing movements, cardiac contractions, and intestinal peristalsis.
The video explains the key problems the technology addresses. More than 90% of drug candidates that pass animal testing fail in human clinical trials due to species differences, while conventional two-dimensional cell cultures cannot replicate the complex three-dimensional architecture of living tissues. Organs-on-a-chip overcome both limitations and simultaneously reduce reliance on animal models. The global organ-on-a-chip market is currently estimated at $120–160 million (2024) and is projected to reach $1–4 billion by 2030–2035.
Viewers learn about the main organ-on-a-chip types and their applications: lung-on-a-chip for modeling infections and toxin exposure; liver-on-a-chip for hepatotoxicity assessment (already cleared by the FDA for preclinical studies); intestine-on-a-chip for studying drug absorption and inflammatory bowel diseases; and placenta-on-a-chip for researching maternal–fetal transport and the mechanisms of preeclampsia. Evgeny Knyazev highlights specific results obtained at the HSE Laboratory of Molecular Physiology, including assessment of chemotherapy permeability using a placenta-on-a-chip model, comparison of intestine-on-a-chip with animal models, and the development of personalized tumor models for therapy selection.
A dedicated section of the video covers the integration of artificial intelligence with organ-on-a-chip platforms: AI enables real-time sensor data analysis, drug toxicity prediction, chip geometry optimization, and accelerated compound screening. Evgeny Knyazev concludes with a balanced technology foresight: the clear advantages of organ-on-a-chip systems — superior predictive power, personalization potential, and ethical benefits — coexist with current limitations including scalability challenges, material selection trade-offs, and the need for standardization. In the long term, the technology promises to cut drug development timelines from 10–15 to 5–7 years and reduce development costs by 50–70%.
The LessON project is supported by HSE University and aims to communicate science to broad audiences. This collaborative release reflects the Laboratory of Molecular Physiology's commitment not only to conducting world-class research, but also to sharing it openly with students, colleagues, and everyone curious about cutting-edge biomedicine.
