The authors regret that several descriptions in the original article were inaccurate. The corrections needed are listed below. These errors do not affect any results, discussion, or conclusions in the original article. 1. In the original caption of Figure 1 we unintentionally omitted a proper citation and statement forpermitted figure reuse. The following sentences should therefore be added to the figure caption: “Theillustration of standard periodontal tissue structure was referenced from Ref. [70]” X.Y. Xu, X. Li, J. Wang, X.T. He, H.H. Sun, F.M. Chen, Stem Cell. Transl. Med., 8 (2019) 392–403. 2. All the abbreviation “PCC” in the original articke should be changed into correct "PCC". 3. Fig. 7a: Previously, the legends 'JP group' and 'SCJP group' were wrongly switched. This has now been corrected. 4. A funder was omitted in the original acknowledgement.
