ONLINE COVER No Escape for Brain Metastases. This image depicts the microenvironment of a breast cancer brain metastasis in a mouse model. The metastasis near the center of the image shows a collection of tortuous, irregular, and abnormally dilated blood vessels (superficial vessels, yellow; deeper vasculature, shades of red). By studying brain metastases and their microenvironment, Kodack et al. determined that the microenvironment directly contributed to drug resistance in metastatic breast cancer and identified a potential therapeutic strategy for treating these challenging tumors.
