(Cell Stem Cell 24, 579–591.e1–e12; April 4, 2019) In the originally published version of our manuscript, one of the authors was incorrectly listed as “Narasimham, P.” To address this, we have now corrected the spelling of the name both here and in our original article online to “Narasimhan, P.” We apologize for the oversight and for any resulting confusion.
