Effects of hybrid scaffolds on BMSC migration in vitro and in vivo. A Structure of the Transwell assay and images of crystalline violet staining for the control group, ECM scaffold group and ECM/GDF-5 scaffold group; B Confocal images of endogenous MSC migration in the defect area at 2 weeks after surgery; C Statistics of the total number of migrating cells in the Transwell assays (n = 3); D Number of double-positive (CD90 and CD105) MSCs at defect sites in vivo (n = 3). Statistical analysis: *p < 0.05, **p < 0.01, ***p < 0.001
