What if gut inflammation, pregnancy hormones, and cancer risk could all be recreated on a chip revealing how disease actually begins?
Researchers at Harvard Medical School and collaborating institutes have developed the most complete colon on a chip model yet for inflammatory bowel disease, offering a closer look at how the condition develops, worsens, and in some cases progresses toward cancer.
The system allows scientists to study inflammatory bowel disease in a controlled human relevant environment, improving understanding of disease triggers and opening pathways toward more precise and personalized therapies.
Unlike conventional models based on animal studies or simplified cell cultures, the chip uses patient derived intestinal cells, including both healthy and inflamed samples from the same individuals. It also replicates real physiological conditions such as fluid flow, immune cell movement, and gut-like stretching, enabling a far more accurate representation of how the human intestine behaves under stress.
The device is built with two microfluidic channels separated by a porous membrane that allows molecular exchange between epithelial and stromal layers. Researchers introduced immune cells, applied mechanical motion to simulate peristalsis, and exposed tissues to hormone environments that mimic menstruation and pregnancy. These conditions revealed stronger inflammation and fibrosis in diseased tissue, along with early cancer associated changes under chemical stress.
The model also enabled early observation of cancer-like transformations in diseased intestinal tissue, offering a new window into how chronic inflammation may evolve into malignancy.
