SSH1 promotes progression of intrahepatic cholangiocarcinoma via p38 MAPK-CXCL8 axis. Building on successful single-cellbased interrogations and recent discoveries in the context of normal development, advanced tumors, as well as premalignancy (albeit to a lesser extent), we anticipate that single-cellguided approaches will help address emerging questions on the evolutionary dynamics of field carcinogenesis. For example, they may cause cells to divide faster which increases the risk for DNA damage. International Journal of Molecular Sciences. FOIA and G.L.
