A novel vehicle-like drug delivery 3D printing scaffold and its applications for a rat femoral bone repairing in vitro and in vivo: Erratum

In our paper ¹, the author has made a mistake by selecting wrong SEM panels during Figure 2 (c, d) and Figure 3 (e, g) preparation of 1393@MBG group. Considering the consistency and the accuracy of SEM data, the authors had repeat experiments and carefully re-examined them by SEM for the refabricated 1393(control group) and 1393@MBG scaffolds. The original figures were attached as supplementary figures. The authors apologize for all these errors and state that these corrections do not change the scientific conclusions of the article in any way.
