Scientists used human pluripotent stem cells to generate human embryonic colons in a laboratory that function much like natural human tissues when transplanted into mice, according to research...
View ArticleFirst-ever autonomously controlled 'capsule robot' explores colon
New research shows that an 18-mm magnetized capsule colonoscope, which can be paired with standard medical instruments, successfully performed intricate maneuvers inside the colon while guided by an...
View ArticleGiardiasis may be a disease of the ecology of the GI tract
Colonization by the human and animal parasite, Giardia, changed the species composition of the mouse microbiome in a way that might be harmful. The research is published in Infection and Immunity, a...
View ArticleFood and antibiotics may change microorganisms in gut, causing IBS
A recent review of research suggests that changes to the microorganisms (microbiota) in the gastrointestinal (GI) tract may be a cause of irritable bowel syndrome (IBS). The review article is published...
View ArticleUltrasound waves propel rapid delivery of RNA to treat colon inflammation
MIT and Brigham and Women's Hospital researchers have demonstrated that they can deliver strands of RNA efficiently to colon cells, using bursts of ultrasound waves that propel the RNA into the cells....
