A reader alerted the journal to duplicated images in Fig. 2C and Fig. 4D of Development (2019) 146, dev175547 ().
In the top panel of Fig. 4D, the bottom part of Stage I and the top part of Stage II-III images show an overlap. This is permissible since spermatogenesis is a continuous process from stage I to stage XII in seminiferous tubules and the panels are all from the same animal. The authors have, however, added an explanation to the legend to avoid any misunderstanding.
The authors mistakenly used the wrong merge image for WT histone H4 in the bottom row when assembling Fig. 2C. The corrected and original figure panels are shown below.
Histone-to-protamine exchange is impaired during spermatogenesis in Phf7 knockout mice. (C) Immunostaining of core histones (H2A, H2B, H3 and H4) (red) in sperm from 8-week-old Phf7−/− and wild-type males. Scale bar: 20 µm.
