Correction: In vivo migration of Fe₃O₄@polydopamine nanoparticle-labeled mesenchymal stem cells to burn injury sites and their therapeutic effects in a rat model

Abstract

Correction for ‘In vivo migration of Fe₃O₄@polydopamine nanoparticle-labeled mesenchymal stem cells to burn injury sites and their therapeutic effects in a rat model’ by Xiuying Li et al., Biomater. Sci., 2019, 7, 2861–2872, DOI: 10.1039/C9BM00242A.

The authors regret errors in Fig. 1c, 3a and 5e in the original article. The corrected figures are shown below. In Fig. 1c, the authors wish to use a different TEM image to the one in Fig. 2a in their previous Biomaterials Science paper.¹ In Fig. 3a, the 100, 150 and 200 μg ml⁻¹ panels have been replaced as the original panels were incorrect leading to partial overlap with the 50 μg ml⁻¹ panel. In Fig. 5e, the MSC and MSC + NPs bands for β-actin have been reversed as the original bands were incorrectly labelled due to being in the wrong orientation.

The raw data for Fig. 3a and 5e were provided by the authors and reviewed by an independent expert.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
