In the Research Article “Cellular senescence inhibits renal regeneration after injury in mice, with senolytic treatment promoting repair” by K. Mylonas et al., an inadvertent image duplication affected Fig. 3C. An immunofluorescent image of collagen I staining and quantification was presented correctly in Fig. 6I alongside a graph quantifying collagen I staining in young nonirradiated versus young irradiated kidneys, but it was accidentally duplicated and shown incorrectly accompanying a different graph of young versus aged kidney collagen I staining in Fig. 3C. Figure 3C has been replaced with a corrected image. The other data and the conclusions in the paper are not affected.
