Critical Limb Ischemia Clinical Trial
Official title:
Efficacy and Safety of Umbilical Cord Artery-derived Perivascular Stem Cells in Patients With Critical Limb Ischemia
This clinical trial included 2 periods. During the first period, it was a single arm study to explore the safety of umbilical cord artery-derived stem cells (UCA-PSCs) in the treatment of patients with critical limb ischemia (CLI). During the second perid, it was a single-center, randomized, controlled prospective study to determine the efficacy of the UCA-PSCs treatment. Those who had CLI were enrolled in the study.
According to the enrollment and exclusion criteria, the patients were enrolled.During the first period, 10 patients were injected with UCA-PSCs/bFGF, a second injection was given 8 weeks later. During the second period, the patients were randomly divided into two groups by computer randomization.Group A was the UCA-PSCs/bFGF group (test group). Group B was the bFGF group (control group). ;
