Western blot analysis of ICAM-1, VCAM-1, and P-selectin; (a) is the results of Western blot; (b), (c), and (d) are ICAM-1, VCAM-1, and P-selectin relative expression after hypoxia exposure. Con, control; hyp, hypoxia; L, H, hypoxia+H EEPO; hypoxia+L EEPO; M, hypoxia+M EEPO; #p<0.05 compared with control group, &p<0.05 compared with hypoxia group, *p<0.01 compared with control group, and ★p<0.01 compared with hypoxia group.
