Summary
Moyamoya disease is a cerebrovascular disease clinically characterized by chronic progressive stenosis or occlusion at the ends of bilateral internal carotid arteries and the origin of anterior cerebral arteries and middle cerebral arteries, followed by the formation of abnormal vascular networks at the base of the skull. Clinically, patients with Moyamoya disease mainly present with ischemic or hemorrhagic stroke, and there are two peaks of incidence in children aged 3-5 and middle-aged people aged 40-50. Moreover, as the pathogenesis and treatment evaluation of Moyamoya disease are still in the research trough at present, new discoveries are prone to occur and thus attract a great deal of attention. It not only has a beneficial promoting effect on the treatment and diagnosis of patients, but also makes it easier for research topics to be reported in top journals.
This study intends to combine iPSC-EVs local skin transplantation with temporal muscle application to promote muscle angiogenesis and the establishment of extracranial and intracranial collateral circulation after temporal muscle application. The above-mentioned design features high efficiency, safety and convenience, and is an innovative exploration both at home and abroad. We hope to screen out safe, efficient and simple preparation methods and transplantation methods of iPSC-EVs through systematic experiments, establish an effective clinical evaluation system, and provide auxiliary means for intracranial and extracranial blood flow reconstruction surgery in the treatment of Moyamoya disease. Moreover, in terms of topic selection, iPSC is currently one of the most promising directions for innovative treatment worldwide.
