Abstract Background: Neural stem cells (NSCs) transplantation has been considered as a potential strategy to reconnect the neural circuit after spinal cord injury (SCI) but the therapeutic effect was still unsatisfied because of the poor inflammatory microenvironment. Previous study reported that neuroprotection and inflammatory immunomodulation were considered to be most important mechanism of NSCs transplantation. In addition, Wnt4 has been considered to be neurogenesis and anti-inflammatory so that it would be an essential assistant agent for NSCs transplantation.Results: We report the first piece of evidence to confirm the interaction between Wnt4-modified NSCs and macrophages using NSCs- macrophages co-cultured system. Wnt4-modified NSCs induce M2 polarization and inhibit M1 polarization of macrophages through suppress TLR4/NF-κB signal pathway; furthermore, M2 cells promote neuronal differentiation of NSCs through MAPK/JNK signal pathway. In vivo, transplantation of Wnt4-modified NSCs improve inflammatory microenvironment through induce M2 polarization and inhibit M1 polarization of macrophages to promote axonal regeneration and tissue repair.Conclusion: The current study indicated that transplantation of Wnt4-modified NSCs mediate M2 polarization of macrophages to promote spinal cord injury repair. Our novel findings would provide more insight of SCI and help with identification of novel treatment strategy.
