Erratum: In vivo tracking of chemokine receptor CXCR4-engineered mesenchymal stem cell migration by optical molecular imaging (Stem Cells International (2017) 10 (8085637) DOI: 10.1155/2017/8085637)

In the article titled “In Vivo Tracking of Chemokine Receptor CXCR4-Engineered Mesenchymal Stem Cell Migration by Optical Molecular Imaging” [1], it was found that the image plates in Figures 1(a), 2(a), and 3(a) were incorrect. The errors are mainly in the published MSC plate images of Figures 1(a) and 2(a) and the MDA-MB-231 plate image of Figure 3(a). The authors confirmed that these corrections do not affect the results and conclusion of the article. The corrected versions of Figures 1-3 are shown below.
