Gene transfection was adopted to overexpress periostin by ADSCs. a Immunofluorescence staining showed that more than 80 % of the ADSCs expressed the periostin protein. By contrast, the control ADSCs lacks the periostin protein. b Western blot analysis showed periostin was highly expressed in P-ADSCs but not in ADSC controls. c Periostin was higher in the P-ADSC group than in the control group (*P <0.05). Scale bar = 100 μm. ADSC adipose-derived stem cell, DAPI 4′,6-diamidino-2-phenylindole, GFP green fluorescent protein, P-ADSC periostin-transfected ADSC
