Effects of adipose stem cell-conditioned medium on the migration of vascular endothelial cells, fibroblasts and keratinocytes

Abstract

Following the publication of the above article, the authors wish to retract the paper for the following reasons. We have further investigated the mechanism of adipose stem cell-conditioned medium in promoting the migration of vascular endothelial cells, fibroblasts and keratinocytes, and have identified that the adipose stem cell-conditioned medium is unable to promote vascular endothelial cell migration at the same rate, or to the same extent. The explanation may be that the vascular endothelial cells used in this study were a cell line, whereas fibroblasts and keratinocytes are primary cells with very different characteristics. Therefore, the experimental results thus obtained suffered from a lack of rigor and scientific accuracy due to the inappropriate selection and application of the cell types used in this study. All the authors agree to this retraction, and we apologize to the readership and to the journal for any inconvenience caused.
