In this Letter, an incorrect micrograph was inadvertently used in the panel entitled ‘Nanog-WT + Scr’ in row 1 of Fig. 3a: the used micrograph was from a different field of view from the ‘EV + Scr’ experiment (see Figure 1). A representative micrograph from the ‘Nanog-WT + Scr’ experiment is presented below. This oversight affects neither the data nor the conclusions of the work presented in the manuscript.
