Author Correction:: Ninjurin1 positively regulates osteoclast development by enhancing the survival of prefusion osteoclasts (Experimental & Molecular Medicine, (2019), 51, 1, (1-16), 10.1038/s12276-018-0201-3)

After online publication of this article, the authors noticed an error in the Fig. 3d section. In Fig. 3d, the authors identified that the WT result (12 hr, lower left) was unintentionally duplicated with the Ninj1^−/− result (12 hr, upper right) during the data organization process. To rectify this duplication, we prepared the correct version of this figure with the proper Ninj1^−/− result (12 hr, upper right). Fig. 3d reveals that transmigration of RANKL-stimulated preosteoclast (red) through the osteoblast monolayer (green) is similar between WT and Ninj1 KO. Thus, our conclusion of a crucial role of Ninj1 in preosteoclast survival is not influenced by the correction. The authors apologize for any inconvenience caused. Fig. 3d in the article. Duplicated images were marked with red rectangles. (Figure presented.) Corrected Fig. 3d. The proper result of Ninj1^−/− (12 hr, upper right) was included. (Figure presented.) The original article has been corrected.
