Developmental Cell 20, 583–596; May 17, 2011 In the course of compiling all the data for this manuscript and preparing composite figures, some confusion arose in labeling and presenting some of the data. In some cases, the similarities between controls and wild-type (e.g., Figures 2A and S3B) made it difficult to distinguish the correct image. In other cases, images were inadvertently swapped or inverted between analogous experiments that showed very similar results (e.g., Figures 4B and 5E). In total, eight subpanels of the main figures were affected, as well as five subpanels of the supplemental material. None of these changes alter the conclusions of the manuscript in any way. A joint review of these errors, conducted by Harvard Medical School and Massachusetts General Hospital, did not find any evidence of research misconduct to warrant further investigation. A complete listing of the affected panels is therefore included below, along with the corrected panels (shown in the context of the entire figures to which they belong). We most sincerely apologize for the confusion that our errors have caused. The corrected panels in the document are: From the main text: Figures 2A (the two leftmost panels for Col2a-Cre mice), 4A (labeling of the nonspecific band), 4B, 5A, 5C, 5E, 5F, and 8A. From the supplement: Figures S3B, S6A, S6C, S7B, and S8C (bottom panel for Ocn-Cre). For clarification, we also include a listing of panels that are unchanged but in which a common control is present in two figures; these reflect cases in which the primary data from the same experiment are divided into two figures. Figure 2A, second panel for Prx-Cre ribs, also in Figure 6C. Figure 4B, bottom-left panels for ‘‘shControl adipo,’’ also in Figure 5E. Figure 5A, panels for ‘‘osteo day 4,’’ also in Figure 8A. Figure 7A, third panels from left for P0 calvaria, also in Figure S8C. Figure S6C, actin panels at bottom, also in Figure S7B.
