Cellular experiments verify that si-p75NTR-BMSCs promote angiogenesis through sortilin. (A) FCM analysis of HUVEC cell cycle. (B) EDU staining for detecting cell proliferation in HUVEC (Magnification: ×200, scale bar = 50 μm). (C) Cell scratch assay to evaluate the migratory ability of HUVECs. (D) WB analysis to measure the expression levels of HIF-1α and VEGF. *P < 0.05 vs. si-NC. #P < 0.05 vs. si-p75NTR
