Figure 5. The expression increase of angiogenesis-related molecules after incubation with exosomes through targeting Hsp70. (A) Western analysis of angiogenesis-related molecule after treatment with si-Hsp70 and RIC exosomes; (B) Protein quantitative analysis of angiogenesis-related molecule after treatment with si-Hsp70 and RIC exosomes; (C) mRNA expression of angiogenesis-related molecule after treatment with si-Hsp70 and RIC exosomes. * P<0.05 compared with the control group. # P<0.05 compared with group si-Hsp70+RIC exosomes.
