We explored the vascular biology of adipose-derived stromal cells (ASCs) from diabetic patients and applied these cells to a murine ischemic flap model to assess the comparative angiogenic potentials between normal and diabetic human ASCs. ASCs were obtained from diabetic patients (n?=?5) and controls (n?=?5). Secretion and expression of angiogenic cytokines were measured under normoxic and hypoxic condition in vitro. Conditioned media harvested from ASC cultures were assessed for their ability to stimulate human umbilical vein endothelial cell proliferation and tubulization. The control and diabetic ASCs were injected into the murine ischemic flaps, and the surviving area was measured. Diabetic adipose-derived stromal cells showed a lower level of vascular endothelial growth factor expression and cell proliferation rates than the control cells (p?
