BMSC-exosomes reduce mechanical allodynia of L5 SNL rats. A Localization of BMSC-exosomes by fluorescence staining; Hind paw PWT (B) and PWL (C) of SNL rats on days 0, 1, 3, 5, 10, 15, and 20 after surgery; (D) TUNEL staining assessed the apoptosis in rat SDH; (E) ELISA measured the expression of TNF-α, IL-1β, and IL-6 in rat SDH. Data were shown as mean ± standard deviation. N = 6. *P < 0.05, vs. the sham group; ^#P < 0.05, vs. the SNL group.
