In the above article, reference 168 (page 210) was incorrectly cited. The citation appeared as: Tamori, Y. & Deng, W. M. Cell competition and its implications for development and cancer. J. Genet. Genom. 38, 483–495 (2011). The correct citation is: Tamori, Y. & Deng, W. M. Tissue repair through cell competition and compensatory cellular hypertrophy in postmitotic epithelia. Dev. Cell 25, 350–363 (2013). This has now been corrected in the online version of the article.
