Scientists grow 'Mini-Guts' to unlock secrets of bowel disease

This study aimed to better understand how the gut repairs itself in people with inflammatory bowel disease (like Crohn's or colitis) and a condition called familial polyposis. Researchers grew tiny 3D models of the gut, called organoids, from small tissue samples taken during routine colonoscopies. By studying these 'mini-guts,' they hoped to learn how specific stem cells and their growth pathways differ in these diseases compared to healthy people.
