Deskripsi

During embryo development, cell fitness determines survival but how this is regulated is unclear. Here, the authors show that in early embryonic development and stem cells exiting the naive state, cells sense the fitness of their neighbours and trigger p53 to repress mTOR to eliminate a third of cells.
