New approach with an unmixing algorithm and 8-channel image acquisition enables multispectral live-cell imaging
Nothing in biology happens in isolation. Complex systems feed interwoven outcomes. Researchers try to unpick individual details, but each cell and molecule must be considered in the context of countless others. Being able to see multiple components of a cell or system simultaneously helps tell the whole story, but typical microscopy techniques have their limits. A new approach enables the use of up to eight colour labels at once, compared to the three or four of many existing technologies, to show multiple elements in detail over time. The team also developed a new protein-binding label and used the technique to study the trafficking of material at the cell surface. An algorithm unmixes overlapping colours to produce images like these bone cancer cells with cell parts labelled in different colours (top right), or particular elements highlighted such as the cell’s cytoskeleton (left and bottom), to help understand everything all at once.

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.
