Abstract

In the original article, there were errors. In the section In Vitro Cellular Evaluation of Composite Scaffold, “Cell Culture”, page 3, an acronym was not given in full at the first mention. The corrected sentence is as follows: “The scaffold (2 mm height and 8 mm diameter) were placed into the 48-well plates, sterilized by immersing in 75% ethanol overnight and washed with phosphate-buffered saline (PBS) for three times by 30 min interval.” Consequently, in the next section “Cell attachment”, the first sentence is corrected as follows: “For cell attachment testing, the scaffolds were harvested at 3 days and washed with PBS for twice, fixed with 2.5% glutaraldehyde at 4°C for 4 h” In Conclusions, page 9, there was a typo in which “was” was used instead of “were,” The corrected sentence is as follows: “The mechanical property and pore diameter of PLGA-MNBG scaffold were significantly improved due to the incorporation of MNBG particles.” In the next sentence, the word “cell” was used incorrectly in “the in vitro cell experiments.” The corrected sentence is as follows: “In addition, the in vitro experiments demonstrated that PLGA-MNBG scaffolds significantly enhanced the mBMSCs attachment, proliferation and osteogenic differentiation at a low MNBG concentration.”.
