    hfNCSC-sEVs are taken up by PCs in vitro and enhance their proliferation and migration. (A) Primary cultures of hfNCSCs were established from male Sprague–Dawley rats. (B) Immunofluorescence staining of the neural crest cell marker p75 (red) and the stem cell marker nestin (green) in hfNCSCs, with 4′,6-diamidino-2-phenylindole (DAPI) staining indicating the nuclei. (C) Western blot analysis demonstrated the presence of surface markers (cluster of differentiation [CD]9, CD81, and tumor susceptibility gene 101 protein [TSG101]) and the absence of an endoplasmic reticulum marker (calnexin) in hfNCSC-sEVs. (D) Nanoparticle tracking analysis was used to quantify the concentration and size distribution of hfNCSC-sEVs. (E) Transmission electron microscopy was used to visualize the characteristic morphology of hfNCSC-sEVs. (F) Immunofluorescence staining indicated that the third-generation PCs cultured in vitro were positive for claudin-1, zonula occludens 1 <t>(ZO1),</t> and glucose transporter 1 (GLUT1) but negative for S100, with DAPI staining marking the nuclei. (G) The internalization of PKH26-labeled hfNCSC-sEVs (red) by ZO1-positive PCs (green) was visualized using immunofluorescence staining, with DAPI staining to mark the nuclei. (H) The Cell Counting Kit-8 assay was used to evaluate the cell viability of PCs across concentrations of 0, 2 × 10 8 , 5 × 10 8 , and 10 × 10 8 particles/mL hfNCSC-sEVs at 3, 5, and 7 days of in vitro culture ( n = 5 per group). (I) The Transwell assay was used to quantify the number of migrating PCs at 6, 12, and 18 hours post-treatment with the aforementioned concentrations of hfNCSC-sEVs, in in vitro culture ( n = 6 per group). (J) Western blot and (K) statistical analyses revealed the relative protein expression levels of proliferating cell nuclear antigen (PCNA) and vimentin in PCs from the phosphate-buffered saline (PBS) and hfNCSC-sEVs groups on day 5 of in vitro culture (normalized to β-actin, n = 3 per group). Data are expressed as the mean ± SEM. * P < 0.05, ** P < 0.01, *** P < 0.001 (one-way analysis of variance and Tukey’s multiple comparison test for H and I; Student’s t -test for K). The data were from at least three separate and independent studies.

(B) Immunofluorescence staining of the neural crest cell marker p75 (red) and the stem cell marker nestin (green) in hfNCSCs, with 4′,6-diamidino-2-phenylindole (DAPI) staining indicating the nuclei. (C) Western blot analysis demonstrated the presence of surface markers (cluster of differentiation [CD]9, CD81, and tumor susceptibility gene 101 protein [TSG101]) and the absence of an endoplasmic reticulum marker (calnexin) in hfNCSC-sEVs. (D) Nanoparticle tracking analysis was used to quantify the concentration and size distribution of hfNCSC-sEVs. (E) Transmission electron microscopy was used to visualize the characteristic morphology of hfNCSC-sEVs. (F) Immunofluorescence staining indicated that the third-generation PCs cultured in vitro were positive for claudin-1, zonula occludens 1 <t>(ZO1),</t> and glucose transporter 1 (GLUT1) but negative for S100, with DAPI staining marking the nuclei. (G) The internalization of PKH26-labeled hfNCSC-sEVs (red) by ZO1-positive PCs (green) was visualized using immunofluorescence staining, with DAPI staining to mark the nuclei. (H) The Cell Counting Kit-8 assay was used to evaluate the cell viability of PCs across concentrations of 0, 2 × 10 8 , 5 × 10 8 , and 10 × 10 8 particles/mL hfNCSC-sEVs at 3, 5, and 7 days of in vitro culture ( n = 5 per group). (I) The Transwell assay was used to quantify the number of migrating PCs at 6, 12, and 18 hours post-treatment with the aforementioned concentrations of hfNCSC-sEVs, in in vitro culture ( n = 6 per group). (J) Western blot and (K) statistical analyses revealed the relative protein expression levels of proliferating cell nuclear antigen (PCNA) and vimentin in PCs from the phosphate-buffered saline (PBS) and hfNCSC-sEVs groups on day 5 of in vitro culture (normalized to β-actin, n = 3 per group). Data are expressed as the mean ± SEM. * P < 0.05, ** P < 0.01, *** P < 0.001 (one-way analysis of variance and Tukey’s multiple comparison test for H and I; Student’s t -test for K).
