Abstract

Adipose-derived stem cells (ASCs) show great potentials in applications such as therapeutic angiogenesis, regenerative medicine and tissue engineering. Pharmacological preconditioning of stem cells to boost the release of cytoprotective factors may represent an effective way to enhance their therapeutic efficacy. In this study, the aim was to determine whether deferoxamine can enhance the release of vascular endothelial growth factor (VEGF) from in vitro expanded ASCs. It is demonstrated that deferoxamine (50-300 μm) upregulated VEGF expression in a concentration- and time-dependent fashion. At the concentrations used, deferoxamine did not show any cytotoxic effects. The stimulatory effect o..
