Brief Summary:
Stroke is a disease with high incidence, disability rate, and mortality rate, ranking as the second leading cause of death globally and the leading cause in China. Acute ischemic stroke (AIS) accounts for approximately 60%-80% of all strokes. The most effective treatments for AIS are revascularization therapies within the time window, including intravenous thrombolysis with tissue plasminogen activator (t-PA) and mechanical thrombectomy. Although t-PA thrombolysis is effective, it can cause reperfusion injury, exacerbating a series of inflammatory damages. Additionally, the success rate of thrombolysis and thrombectomy is closely related to the onset time. The time window within 4.5 hours or 6 hours is considered effective for rescuing the ischemic penumbra, and only a minority of AIS patients can receive thrombolytic therapy. Some patients have contraindications to thrombolysis, and endovascular treatment is only suitable for large vessel occlusion. Furthermore, in China, low public awareness of early disease recognition, insufficient prehospital emergency capabilities, in-hospital emergency delays, and other factors lead to delayed AIS treatment and a low thrombolysis rate.
Studies have shown that mesenchymal stem cells can reduce the infarct area and alleviate blood-brain barrier damage by regulating the microenvironment of damaged brain tissue, alleviating inflammatory responses, and promoting angiogenesis, neurogenesis, and neurovascular repair. This study aims to evaluate the efficacy, safety, and tolerance of single and multiple intravenous infusions of hUC-MSCs injection in the treatment of AIS patients.
