Figure 5.Analysis of mRNA and protein expression of CXCR4, SDF-1, and VEGF in lung tissue. (A) mRNA levels of CXCR4, SDF-1, and VEGF were evaluated by qRT-PCR. (B) Protein expression analysis of CXCR4, SDF-1, and VEGF by western blotting. Data are presented as the mean ± SD. *P < 0.05 compared with the control group; #P < 0.05 compared with the BPD group; △P<0.05 compared with the EPO; ▲P<0.05 compared with the MSCs group.
