Innovative organ-on-a-chip technology could shed light on cell behavior in liver cancer

Overview of liver chips. The chip, formed from clear flexible polymers, is split into two channels (1,4) separated by a porous membrane (3). Primary human liver sinusoidal endothelial cells (LSEC) (5) were seeded into the bottom channel (4). Following confirmation of LSEC confluence using brightfield microscopy, epithelial cells (Huh-7) (2) were seeded into the top channel. The chip can be connected to a flow system termed Zoe, allowing media to be perfused through the chip at variable flow rates. Credits: Frontiers in Cell and Developmental Biology (2024).

In a stride toward enhancing cancer treatment, University of Birmingham researchers are using organ-on-a-chip technology to imitate the liver’s environment and improve immunotherapy for liver cancer.

This innovative approach, detailed in an article published in Frontiers in Cell and Developmental Biologyaims to overcome the challenges faced by current immunotherapies in treating solid organ cancers, where immune cells struggle to reach and effectively target tumor cells.

The study, set up in partnership with the Organ-on-a-Chip Technologies Network and co-authored by Professor Shishir Shetty, Professor Alicia El Haj and colleagues including James Kennedy and Scott Davies, was a collaboration between the Inflammatory Liver Disease and Next -Generation Therapies research themes at the NIHR Birmingham Biomedical Research Center (BRC).

It demonstrates the potential of organ-on-a-chip technology to simulate the human liver’s blood vessels, allowing for a better understanding of how immune cells navigate the blood stream and cross blood vessels to attack cancer cells.

The research team successfully grew cells from human liver blood vessels in the chip, delivered human immune cells into the chip, and confirmed their capture and adhesion by observing them with microscopes using confocal and multiphoton imaging.

Shishir Shetty, Professor in Liver Tumor Immunology at the University of Birmingham’s Institute of Immunology and Immunotherapy, Cancer Research UK Advanced Clinician Scientist and co-theme lead of the BRC’s Inflammatory Liver Disease research theme, and Honorary Consultant Hepatologist, said,

“Our initial results are promising, showing that we can closely mimic the liver’s environment and track the behavior of immune cells in real-time. We hope that this establishes a platform to test treatments that enhance the efficacy of immunotherapy for liver cancer patients.”

Organ-on-a-chip technology represents a significant advancement in biomedical research, providing a more accurate in vitro model of human organs. By integrating microfluidic cell culture techniques, researchers can replicate the physiological responses of organ systems, offering a promising alternative to animal testing and potentially accelerating the development of new therapies.
