Correction: Impaired autophagy triggered by HDAC9 in mesenchymal stem cells accelerates bone mass loss (Stem Cell Research & Therapy, (2020), 11, 1, (269), 10.1186/s13287-020-01785-6)

Following the publication of the original article [1], the authors identified image overlap in Figs. 2d, 3c and 6c. The image misuse was due to mislabeling of the original data. The authors checked the original data and wish to replace the representative Oil red O staining image of siHDAC9 in Fig. 2d and the LC3 immunofluorescence staining of 16 m + shSCr in Fig. 6c. These corrections do not affect the original conclusions. The authors apologize for any inconvenience that the errors may have caused. The correct figures have been included in this correction.
