Exosomal miR-21 participates in EA by promoting the proliferation of SC and the expression of NTFs. (a) Immunofluorescence staining of S-100α (red). The nuclei were visualized using DAPI (blue). Bar = 50 μm. (b) Immunofluorescence staining of NGF, BDNF, and GDNF (green). Bar = 20 μm. (c) Mean fluorescence intensity of S-100α. ∗∗P < 0.01 compared with the model group; ##P < 0.01 compared with the EA group. Mean fluorescence intensity of NGF, BDNF, and GDNF (d–f). ∗P < 0.05; ∗∗P < 0.01 compared with the model group; ##P < 0.01 compared with the EA group; &P < 0.05 compared with the EG group.
