Effects of periostin on the apoptosis of ADSCs under hypoxia. Apoptosis of GFP-ADSCs transfected with or without periostin under hypoxia a or normoxia b was analyzed using flow cytometry analysis. The apoptosis rates c indicated that overexpression of periostin effectively enhanced the viability of ADSC. Western blotting analysis revealed that the levels of anti-apoptotic Bcl-2 increased and pro-apoptotic Bax decreased d, and RT-PCR e showed that the ratio of Bcl-2/Bax was significantly higher in P-ADSCs than in ADSCs in normoxic and hypoxic treatments. *P <0.05.
