Following publication of the original article [1], the authors identified that there are image overlap in the Alizarin red staining experiment in Fig. 6G EV and Fig. 6C miR-NC, Fig. 6C miR-431M, Fig. 6I si-ROCK1+EV and Fig. 6G si-ROCK1 during figure assembling. The corrected image of the Alizarin red staining experiment has been updated in Fig. 6. These errors do not affect the discussion or conclusions in the article. We, the authors regret making this mistake.
