As tumors grow, they outpace the surrounding blood vessels' ability to provide enough oxygen, a state known as hypoxia. Rather than killing the tumor, however, hypoxia triggers changes in cancer cell metabolism that actually promote tumor growth and spread. Understanding more about hypoxia in cancer cells may help researchers find better ways of managing the disease. This image of a mouse model for HER2-positive breast cancer uses a novel imaging technique called transparent tumor tomography that three-dimensionally visualizes the tumor microenvironment at a single cell resolution. Hypoxic areas are in green; HER2 proteins in blue; CD31 endothelial cells in red.
