Liver Metastasis of Human Prostate Cancer (IMAGE) Purdue University Caption Researchers have discovered a link between prostate cancer aggressiveness and a compound called cholesteryl ester accumulated in lipid droplets inside single cancer cells. This image shows liver metastasis of human prostate cancer, taken using a technique called stimulated Raman scattering microscopy. The bright dots represent intracellular lipid droplets enriched in cholesteryl ester. A publication-quality image is available at http://news.uns.purdue.edu/images/2014/cheng-prostate.jpg.
