Corrected-article in Int J Biol Sci, Volume 16, 1821

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.

Figure 2, Figure 3 and the legends should be corrected as follows.

 Figure 2 

FESEM images of (a, c) as fabricated 1393 and 1393@MBG scaffold; (b, d), the cross section of as fabricated 1393 and 1393@MBG scaffold.

 Figure 3 

(a, b) FESEM images and the surface profile of as fabricated 1393 scaffold; (c, d) after 30 days immersed scaffold; (e, f) FESEM image and the surface profile of as fabricated 1393@MBG scaffold; (g, h) after 30 days immersed scaffold; (i) The Ra of 1393 and 1393@MBG scaffold surface when immersed from 0 to 30 days; (j) The compressive strength of the 1393 and 1393@MBG scaffold on day 0, 30 and 90. mean ± SD, n = 5. *Significant difference when compared to 1393 (p < 0.05).
