Race to the bottom: Darwinian competition in early intestinal tumorigenesis

Abstract

Mutant oncogenes could enable clonal dominance by cell-intrinsic means or by suppressing nearby wild-type stem cells. Reporting recently in Nature, three groups demonstrate potent neighborhood effects, both within intestinal crypts (Flanagan et al., 2021; van Neerven et al., 2021) and across crypts through intermediary sub-epithelial trophocytes (Yum et al., 2021).
