This article has been corrected: The authors found an error in Figure 5G, which depicts transwell migration assays assessing the effects of miR-15a-3p inhibition on HUVEC cells. The central panel, illustrating migration of HUVECs treated with exosomes derived from DFU individuals (Dia-Exos), was replaced with the appropriate image from the original set of experiments. This inadvertent error does not in any way compromise the validity or integrity of the study's findings. The authors take full responsibility for this oversight and sincerely apologize for any inconvenience caused.
