Upregulating CXCR7 expression accelerated reendothelialization and inhibited neointimal hyperplasia. a Representative images of Evans blue staining (bar = 500 μm; n = 5 per group). b Reendothelialization rate in different groups after 7 days. c Reendothelialization rate after 14 days. d I/M ratio of HE-stained EPCs 21 days after treatment (bar = 150 μm; n = 5 per group). e Neointimal area assessed by Masson trichrome staining 21 days after treatment (bar = 150 μm; n = 5 per group) (*p < 0.05; **p < 0.001)
