Xenogenic Implantation of Equine Synovial Fluid-Derived Mesenchymal Stem Cells Leads to Articular Cartilage Regeneration

Figure 4

Fluorescent imaging of MSCs. Representative images to show (a) DiI-positive MSCs before implantation. (b) Absence of DiI-positive MSCs in the control group, and (c) DiI-positive MSCs in the treated groups. Arrows indicate the persistence of DiI-labeled MSCs at least 1 week postimplantation, suggesting the localization of cells at the injury site.
