PG - 1756286419859725 LID - 10.1177/1756286419859725 [doi] LID - 1756286419859725 AB - BACKGROUND: Therapeutic applications of stem cells, especially mesenchymal stem cells, were once regarded as a promising therapy for mitigating acute cerebral infarction. Unfortunately, all the stem cell clinical trials have been futile. A new stroke therapeutic strategy of combining stem cells with nanotechnology has recently gained significant attention. The objective of this study was to evaluate the application of cerium oxide nanoparticle (nanoceria)-labeled human umbilical cord mesenchymal stem cells (HucMSCs) for stroke therapy. METHODS: In our study, cerium oxide nanoparticles were precovered with hyaluronic acid before labeling HucMSCs and the synergistic effects from both HucMSCs and cerium oxide nanoparticles were analyzed in in vivo and in vitro experiments. RESULTS: The nanoceria-labeled HucMSCs combined advantages from both sides, including the capacity for inflammatory modulation of HucMSCs and the antioxidant effects of nanoceria. Compared with either HucMSCs or nanoceria individually, nanoceria-labeled HucMSCs exerted significantly enhanced capacities after gaining combined antioxidant and anti-inflammatory effects. CONCLUSION: Our findings suggest a novel strategy with effective and well-tolerated applications of stem cells for acute cerebral infarction therapy after modification of cells with nanomaterials.
