Abstract

Allogeneic umbilical cord blood is regarded as a beneficial source of stem cells with varying therapeutic potential. On the other hand, cerebral palsy is one of the neurological conditions that are the primary contributor to early childhood disability. The aim of this systematic review was to harvest data from currently available sources to determine the safety and efficacy of treating cerebral palsy patients with stem cells obtained from allogeneic umbilical cords. For this study, systematic searches of the databases PubMed, Scopus, Web of Science, Embase, ScienceDirect, and Google Scholar were conducted with no time Limit until November 2022. Duplicates were found and eliminated after entering the data from the chosen studies into the Endnote reference management program. The remaining studies were assessed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses phases and the inclusion and exclusion criteria (PRISMA). The search was performed using the keywords of Safety, Effectiveness, Stem Cells, Cerebral Palsy, and Umbilical and the (AND) and (OR) operators and their combinations were used to construct the search strategies. After several assessments and based on the inclusion and exclusion criteria, 31 of the remaining 58 studies were eliminated. The systematic review method included 7 final studies in the end. Based on the reviewed studies, it was reported that umbilical cord blood is currently one of the best sources of adult stem cells…

How strong is the evidence?
