Abstract
Epithelial-to-Mesenchymal Transition (EMT) is a form of embryonic cell plasticity reactivated in adult cells during injury and cancer. A recent study by Perelli et al. demonstrates that EMT confers an evolutionary advantage to tumors by inducing chromosomal instability, structural genomic rearrangements and chromothripsis, thus favoring the emergence of high-fitness malignant clones.
