Detection of paracrine factors in the G-ADSC-Exos. The ELISA showed that the expression of VEGF, IGF-1, and FGF were significantly upregulated in the G-ADSC-Exos than the ADSC-Exos, but the differences in the expression of TNF-α, HGF, PDGF, and EGF were not significant between the two groups. All experiments above were repeated three times (n = 3). A two-tailed Student’s t-test was performed to compare data between groups. *P < 0.05; G-ADSC-Exos, G-ADSC-derived exosomes
