Autologous Endothelial Progenitor Cells Transplantation for Chronic Ischemic Stroke

Stroke is a frequently occurring and common diseases in nervous system,and most of the survivors will remain disorders of motor,sensory and cognition function.It will brought heavy burden to patients themselves,their family and society.Drugs,rehabilitation excise and hyperbaric oxygen will improve functions after acute stroke.However,in the chronic ischemic stroke,there was few methods to improve the functions.In recently research,stem cell will be a new methods to improve the neural function after through differentiate to nervous cells and secrete some neurotrophic factors to repair the damage. In this study, the investigators will assess the safety and feasibility of intracerebral transplantation of autologous endothelial progenitor cells in patients with chronic ischemic stroke. The neurological outcome will be determined after transplantation.
