New frontiers in cell competition†

Abstract: Cellular communication is at the heart of animal development, and guides the specification of cell fates, the movement of cells within and between tissues, and the coordinated arrangement of different body parts. During organ and tissue growth, cell-cell communication plays a critical role in decisions that determine whether cells survive to contribute to the organism. In this review, we discuss recent insights into cell competition, a social cellular phenomenon that selects the fittest cells in a tissue, and … Show more

“…In ESCs, the exit from self-renewal into differentiation triggers cell competition and associated apoptosis (de Beco et al, 2012;Levayer and Moreno, 2013;Wagstaff et al, 2013). Hence, selective apoptosis is perhaps triggered as a result of PrE differentiation, and this is suppressed by limiting concentrations of LIF.…”

“…In contrast to the classical cell autonomous responses of growth arrest or apoptosis, a noncell autonomous mechanism called cell competition, first uncovered in Drosophila, determines whether a cell is to survive or be eliminated based on its relative "fitness" in comparison with its neighboring cells (12,13). Therefore, otherwise viable but less-fit cells may be eliminated in a competitive environment to ensure the overall fitness of the tissue and, in turn, the organism.…”

“…In flies, the Hippo pathway has been implicated as a driver of cell competition upstream of myc (Neto-Silva et al 2010;de Beco et al 2012). The pathway con-sists of a kinase cascade (consisting of the Hippo and Warts kinases), which negatively regulates a transcriptional coactivator (Yorkie).…”
