Knockdown of Nrf2 attenuated the functional activity of CXCR7-EPCs. a Differences in adhesion capacity among all groups (bar = 100 μm; n = 5). b Differences in repair capacity among all groups (bar = 200 μm; n = 5) (*p < 0.05, compared with control group; &p < 0.05, compared with group CXCR7-EPCNrf2-KD group)
