Macrophage migration inhibitory factor (MIF) enhances disease aggressiveness and the metastatic potential of pancreatic cancer cells by inducing epithelial-to-mesenchymal transition (EMT). This image, obtained with confocal microscopy, shows enhanced vimentin expression (pink), a mesenchymal marker, in pancreatic cancer cells stably overexpressing MIF.
