Fig 1: DBM-MSN/152RM scaffolds coordinate the recruitment of MSCs and ECs in vivo. (A) HE staining images demonstrating the recruitment of MSCs and ECs 1 week after DBM, DBM-MSN, DBM/152RM and DBM-MSN/152RM scaffold implantation (n = 5 rats per group). Scale bar, 100 µm. (B) Co-immunofluorescence staining of CXCR4, integrin avß3 and CD271 in MSCs from 1 week after DBM, DBM-MSN, DBM/152RM and DBM-MSN/152RM scaffold implantation (n = 5 rats per group). Scale bar, 100 µm. (C) Immunofluorescence staining of CD90+CD105+ MSCs from 1 week after DBM, DBM-MSN, DBM/152RM and DBM-MSN/152RM scaffold implantation (n = 5 rats per group). Scale bar, 100 µm. (D) Co-immunofluorescence staining of emcn and integrin avß3 in type H vessels from 4 weeks after DBM, DBM-MSN, DBM/152RM and DBM-MSN/152RM scaffold implantation (n = 5 rats per group). Scale bar, 100 µm. (E) Immunofluorescence staining of CD31+ in EPCs from 4 weeks after DBM, DBM-MSN, DBM/152RM and DBM-MSN/152RM scaffold implantation (n = 5 rats per group). Scale bar, 100 µm. Data are shown as the mean ± SD. ns P > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001; ANOVA was employed. For all panels in this figure, data are representative of three independent experiments.
