Abstract

Bile duct hyperplasia in rodents, caused by chemical cytotoxicity, bile flow interference, or aging, is traditionally assessed through time-consuming microscopic examination by pathologists. We developed a deep learning-based, artificial intelligence (AI) model for quick and accurate assessment of bile duct hyperplasia in mice. The study utilized 127 hematoxylin and eosin-stained, mouse liver whol…
