Replacement Pancreatic Cells

Replacement Pancreatic Cells

Beta cells of the pancreas produce insulin – the hormone that controls uptake of glucose into the tissues. In type I diabetes these beta cells are rapidly destroyed by the immune system, while in type II diabetes beta cell numbers dwindle only as the disease progresses – its primary characteristic being insulin resistance. Replacement pancreatic cells, like the ones pictured, including insulin-producing cells (red), have been derived from human embryonic stem cells and used to successfully treat type I diabetes in mice. But whether such cell replacement would be effective in treating type II diabetes, given the underlying insulin resistance, was uncertain. Now researchers have found that indeed the treatment does work in type II diabetic mice, when combined with existing diabetic drugs. Type II diabetes accounts for more than 90 percent of all cases of the disease, so having a new possible treatment on hand could make a vast clinical impact.

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.
