Meso-scale spatial analysis of papilloma formation and clonal expansion in cancerized skin.
Somatic driver mutations pervade phenotypically normal epithelia, yet only a minority of clones progress to tumors. To understand how tissue context modulates clonal selection, we apply the classical two-stage DMBA/TPA model of carcinogenesis to mouse back skin. We collect coordinate-registered, meso-scale grids spanni...
