A reader recently contacted the Editors regarding possible duplication of portions of the images presented in Figure 3, A–C, and Figure 4, A and B, that were used to represent distinct samples. The Editors have requested that the corresponding author provide the original data supporting these figures; however, these data are no longer available. As we are unable to evaluate the integrity of these figures, we are publishing this notice to alert readers to the concern.
