The liver doesn't have an easy existence. As the body's filters, liver cells (one pictured) – or hepatocytes – are constantly bombarded with nasty substances that they fight to remove from the bloodstream. This front line function means that if you consume anything genuinely dangerous, they are invariably going to bear the brunt. Hepatocytes therefore are ideal for investigating drug toxicity because if the liver can't deal with a substance, chances are it's going to do your body more harm than good. But the problem is getting enough of them. Current methods for growing them in the lab do help to fulfil the high demand but fail to perfectly imitate naturally-occurring cells. A new technique that uses 3D scaffolds to guide growth produces hepatocytes that are more realistic, and better suited to a life of punishing drug trials. It’s a tough job… but someone’s got to do it.

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.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
