HGF promoted HFSCs differentiation. A and E The cell showing green fluorescence represents HFSCs that were transduced with the viral vector carrying HGF gene. B and F Immunofluorescent staining of DCX and NeuN with red fluorescence. C and G DAPI staining emitted blue fluorescence at 405 nm. D and H The merged images of EGFP, DCX or NeuN and DAPI. Bar = 10 µm. I and J The statistical analysis of the percentages of double-stained HFSCs in total EGFP-expressing HFSCs in different groups. Values are the mean ± SD. *P < 0.05 Saline group vs. Control group, ^#P < 0.05 HFSCs group vs. Saline group, ^∆P < 0.05 HFSCs/HGF group vs. HFSCs/Vehicle group, n = 6
