Human gut chip reveals three hidden drivers behind IBD damage and cancer risk

Researchers used donor-derived human colon chips from IBD patients and healthy tissue to study disease drivers in a human-relevant model.

IBD-linked fibroblasts, mechanical stretching, and pregnancy-level hormones all worsened inflammation and fibrosis in the chips.

Exposure to a carcinogen plus IBD fibroblasts increased early cancer-related changes, including CEACAM5 signals.

The work suggests gut chips may explain IBD severity and cancer risk better than animal models, and could improve drug testing.
