Front Cover: Motile hepatocellular carcinoma cells preferentially secret sugar metabolism regulatory proteins via exosomes

DOI: 10.1002/pmic.201700103 The cover image has four major elements: 1) Cells in blue and red differentiate motile and non‐motile liver cancer cells, respectively; 2) secretion of their exosomes are in the same colors; 3) a MS spectrum depicts the comparative proteomics analysis on exosomes; 4) exosomal proteome signatures are shown in two blocks to illustrate the major findings of this study. Specifically, the core message, which sugar metabolism units in exosomes can reflect liver cancer cell motilities, can be easily told by this image.
