Vascularization and osteogenesis in ectopically implanted bone tissue-engineered constructs with endothelial and osteogenic differentiated adipose-derived stem cells

Figure 1 Relative endothelial-related gene expression in uninduced adipose-derived stem cells. Relative endothelial-related gene expression in uninduced adipose-derived stem cells at the 12th day after the third passage (P03-12d cells) compared to uninduced adipose-derived stem cells obtained 1 d after the third passage (P03-1d cells; calibrator sample). Upregulation of expression of all examined endothelial-related genes (Vwf, Egr1, Flt1 and Vcam1) was found in P03-12d cells. Vwf: Von Willebrand factor; Egr1: Early growth response 1; Flt1: Vascular endothelial growth factor receptor 1; Vcam1: Vascular cell adhesion molecule 1.
