A Prospective Open Non-randomized Phase III Study of Therapeutic Angiogenesis in Diabetic Patients With Critic Ischemia of Lower Limbs While Administering Positive CD133 Mobilized With G-CSF The primary objective is to analyze the safety and efficacy of CD133 cells obtained from peripheral blood in the treatment of diabetic patients with critic ischemia in lower limbs.
Tumor angiogenesis has both predictive as well as therapeutic implications. Several clinical studies have correlated the extent of angiogenesis with prognosis of cancer patients. Folkman Tumor Angiogenesis Therapeutic Implications New England Journal of Medicine Vol.
Mechanisms clinical implications and therapeutic strategies. Compelling data implicate angiogenesis and tumor-associated neovascularization as a central pathogenic step in the process of tumor growth invasion and metastasis. These complex processes involve multiple steps and pathways dependent on the local balance.

If the relationship between psoriatic epithelium and its capillary endothelium turns out to be similar to the integration of capillaries by solid tumors then âœanti-angiogenesisâ may eventually become a useful therapeutic approach in psoriasis. Numerous anti angiogenic agents were developed successfully for the treatment of renal cell carcinoma lung cancer breast cancer brain tumors and colorectal carcinoma but resistance to these therapies soon emerged. In contrast in pathological conditions such as malignant growth atherosclerosis and diabetic retinopathy angiogenesis becomes persistent due to an imbalance in the interplay between the positive and negative regulatory signals controlling the process.
Thus the control of tumor neovascularization may lead to new therapeutic approaches. Angiogenesis the process of new capillary formation from a pre-existing vessel plays an essential role in both embryonic and postnatal development in the remodeling of various organ systems and in several pathologies particularly cancer. From the global sensitivity analysis we derive the following therapeutic implications.
I at small tumor sizes it is better to perturb the tumor growth rate by targeting cancer cells directly and ii manipulation of the vascular supply by increasing inhibition or decreasing stimulation is the most promising approach when tumors have grown to a substantial size. However from a therapeutic perspective it is believed that vasculogenesis leads only to an immature poorly functional vasculature and therefore angiogenesis is the main therapeutic target. The mechanism of angiogenesis consists of several stages and involves a set of growth factors substrate molecules and multiple cell types.
Tumor oxygenation status is tightly regulated and correlates with its aggressive behavior. Hypoxia plays critical roles in tumor progression including tumor angiogenesis mutation rate metastasis and resistance to radiation and chemotherapy. Many molecular pathways have been recognized to mediate these hypoxia-induced responses in tumors.
The inhibition of angiogenesis is an attractive therapeutic approach to control tumor progression 6. PDT mechanism of action is the local generation of cytotoxic singlet oxygen 1 O2 which.
