Coaxing Colons

Coaxing Colons

The gastrointestinal tract – the oesophagus, stomach and intestine – can suffer a host of diseases. General symptoms of gastrointestinal diseases can range from constipation and diarrhoea to vomiting. Because studying equivalent animal organs can’t precisely demonstrate how gastrointestinal diseases manifest in humans, researchers turned to engineering human stem cells to generate life-like colon tissue in the lab. To do so, they had to identify the correct genetic and molecular markers that could be used to precisely coax the stem cells into human colon organoids (pictured highlighting different molecules with various fluorescent colours). Researchers transplanted these organoids just under the surface of the kidney in mice – which provides a nutritious place for them to carry on growing – and saw that they adopted the form, structure and molecular properties of the human colon. In-depth research into the diseases of the colon can now be carried out effectively within this human model system.

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
