Expression of HIF-1α and NRF2 by MSCs pretreated with inflammatory factors. MSCs were pre-stimulated by inflammatory cytokines IFN-γ and TNF-α for 12 h. a Real-time PCR analysis of the expression of HIF-1α mRNA in MSCs. b Real-time PCR analysis of the expression of NRF2 mRNA in MSCs. c Western blot analysis of the protein expression of HIF-1α in MSCs. d Western blot analysis of the protein expression of NRF2 in MSCs.^** p < 0.01
