Exo-Gel promoted Exo retention in the ankle. A Schematic diagram of experimental design. The DiR-labeled Exo (4 µg/2 µl) was injected with or without hydrogel to subtalar joint after transecting ATFL/CFL, to establish ankle-subtalar joint complex instability. (B) Representative in vivo fluorescence imaging of ankle at 3, 7, 14, and 28 d after transplantation of Exo-Gel or Exo alone. B Quantitative analysis of fluorescence intensities of ankle-subtalar joint after transplantation of Gel incorporating Exo or Exo alone. Data are expressed as means ± SEM (n = 3). *p < 0.05
