Abstract
Expression of Concern for: ‘3D-printed dimethyloxallyl glycine delivery scaffolds to improve angiogenesis and osteogenesis’, Zhu Min et al., Biomater. Sci., 2015, 3, 1236–1244, https://doi.org/10.1039/C5BM00132C.
Biomaterials Science is publishing this expression of concern in order to alert our readers that we are presently unsure of the reliability of the data in Fig. 3 and 4 of the article.
The Royal Society of Chemistry has asked the affiliated institution (Shanghai Sixth People's Hospital, Shanghai Jiaotong University) to investigate this matter and confirm the integrity and reliability of the data. An expression of concern will continue to be associated with this manuscript until we receive information from the institution on this matter.
