Abstract: It has now been discovered that p53 is a potent inhibitor of angiogenesis and arteriogenesis. Inhibition of p53 stimulates angiogenesis, arteriogenesis and improves perfusion in limbs. Therefore, methods are provided for treating diabetic-induced ischemia in a subject in need thereof comprising locally administering a therapeutically effective amount of one or more p53 molecule inhibitors or analogs and derivatives thereof to a site of ischemic tissue in the subject. Methods are provided for improving limb perfusion in a subject in need thereof comprising locally administering a therapeutically effective amount one or more p53 inhibitors together with a therapeutic agent or separately from the therapeutic agent to cells of a limb of a subject in need thereof.
