Brief Summary:
This clinical trial is a clinical trial for the evaluation of the safety and efficacy of umbilical cord blood (UCB) therapy, UCB and erythropoietin (EPO) combination therapy in adult stroke patients.

Condition or disease Intervention/treatment Phase
Stroke Umbilical Cord Blood Erythropoietin Safety Treatment Outcome Drug: Umbilical cord blood infusion Drug: Erythropoietin injection Drug: Placebo umbilical cord blood infusion Drug: Placebo erythropoietin injection Procedure: Active rehabilitation Phase 1 Phase 2

Detailed Description:

UCB is a high-quality source of mesenchymal stem cells, and studies are being actively developed for stroke patients. UCB therapy has a neuroprotective effect through anti-inflammatory effect and anti-apoptosis.

However, UCB alone has not been able to provide sufficient improvement and is being studied for combination therapies with growth factors that can exert its effects. Among the various growth factors, EPO is a powerful factor that can act as a neurotrophic factor in neurons, astrocytes, oligodendrocytes, microglia, endothelial cells, and neural stem/precursor cells.

In our previous study of subacute stroke animal models, investigators confirmed that the combined administration of UCB and EPO improved the behavioral assessment (mNSS, Cylinder test) compared to UCB only administration.

The aim of this study is to investigate the difference in therapeutic effects between UCB alone therapy and UCB and EPO combination therapy.

Drug: Placebo umbilical cord blood infusion
Placebo umbilical cord blood infusion is administered intravenously and is performed at the stem cell clinical trial center. The procedure is performed by the doctor who is enrolled in this study. Monitor pulse and oxygen saturation during the procedure.
Other Name: pUCB

Drug: Placebo erythropoietin injection

Experimental: UCB infusion and placebo EPO injection group
Take immunosuppressant agents for 1 week. Umbilical cord blood is administered in the treatment room. Afterward, the venous erythropoietin placebo injects into the peripheral vein 5 times a total of 5 times a week.
