Subsequent to publication of this paper online the authors have realized that there was an error in Fig. 1f. The authors inadvertently misused SEM images BMSCs seeded onto a HA/RSF scaffold after 14 days in Fig. 1f. The correct figures are given below. The error in the displayed image does not alter the validity of the work and the conclusions. The authors apologize to readers for these errors.
