Human umbilical cord blood-derived mesenchymal stem cells therapy for cerebral infarction in animal model: A meta-analysis
Abstract
Aim: Cerebral infarction (CI) is a serious cerebrovascular infarction disease. In recent years, the use of human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) has received attention as a new alternative for treating CI in animal model. This systematic review evaluated the efficacy and safety of hUCB-MSCs, using as a treatment in improving functional recovery of CI in animal model. Methods: Electronic databases through July 5, 2023 were searched to identify relevant studies that controlled hUCB-MSCs treatment studies focusing on CI in animal model. We independently selected and assessed the relevant studies. Results: 27 studies that fulfilled the inclusion criteria were included. Compared with control group, significant beneficial effects were observed in hUCB-MSCs group regarding the neurological deficit scores (mean difference [MD]: −1.57, 95% confidential interval [CI]: −2.06, −1.08, P<0.00001), infarct size (MD: −2.82, 95% CI: −4.14, −1.49, P<0.0001).
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in animal, not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
