UC blood hematopoietic stem cells and therapeutic angiogenesis.
Studies suggest that mobilized hematopoietic stem cells (HSC) are recruited to ischemic tissue and stimulate angiogenesis. Critical observations in pre-clinical studies have identified an augmentation of endogenous microvascular collateralization that is beyond that directly attributable to anatomic incorporation and differentiation of infused human cells into the vascular endothelium. Evidence links age-associated reductions in the levels of circulating marrow-derived HSC characterized by expression of early HSC markers CD133 and CD34, with the occurrence of cardiovascular events and associated death. Utilizing the patient's own HSC to augment angiogenesis has several disadvantages, including reduced function of these cells and logistical issues related to cell collection from individual patients. Thus an available source of allogeneic HSC such as UC blood for cellular therapy may be optimal.
