INTRODUCTION: Spinal cord injury (SCI) is a significant global health challenge that results in profound physical and neurological impairments. Despite progress in medical care, the treatment options for SCI are still restricted and often focus on symptom management rather than promoting neural repair and functional recovery. This study focused on clarifying the impact of Schwann cell (SC) transplantation on the molecular, cellular, and functional basis of recovery in animal models of SCI.
MATERIAL AND METHODS: Relevant studies were identified by conducting searches across multiple databases, which included PubMed, Web of Science, Scopus, and ProQuest. The data were analyzed via comprehensive meta-analysis software. We assessed the risk of bias via the SYRCLE method.
RESULTS: The analysis included 59 studies, 48 of which provided quantitative data. The results revealed significant improvements in various outcome variables, including protein zero structures (SMD = 1.66, 95 %CI: 0.96-2.36; p < 0.001; I2 = 49.8 %), peripherally myelinated axons (SMD = 1.81, 95 %CI: 0.99-2.63; p < 0.001; I2 = 39.3 %), biotinylated dextran amine-labeled CST only rostral (SMD = 1.31, 95 % CI: 0.50-2.12, p < 0.01, I2 = 49.7 %), fast blue-labeled reticular formation (SMD = 0.96, 95 %CI: 0.43-1.49, p < 0.001, I2 = 0.0 %), 5-hydroxytryptamine caudally (SMD = 0.83, 95 %CI: 0.36-1.29, p < 0.001, I2 = 17.2 %) and epicenter (SMD = 0.85, 95 %CI: 0.17-1.53, p < 0.05, I2 = 62.7 %), tyrosine hydroxylase caudally (SMD = 1.86, 95 %CI: 1.14-2.59, p < 0.001, I2 = 0.0 %) and epicenter (SMD = 1.82, 95 %CI: 1.18-2.47, p < 0.001, I2 = 0.0 %), cavity volume (SMD = -2.07, 95 %CI: -2.90 - -1.24, p < 0.001, I2 = 67.2 %), and Basso, Beattie, and Bresnahan (SMD = 1.26, 95 %CI: 0.93-1.58; p < 0.001; I2 = 79.4 %).
CONCLUSIONS: This study demonstrates the promising potential of SC transplantation as a therapeutic approach for SCI, clarifying its impact on various biological processes critical for recovery.
