There is urgent need to improve the clinical outcome of peripheral nerve injury. Many efforts are directed towards the fabrication of bioengineered conduits, which could deliver stem cells to the site of injury to promote and guide peripheral nerve regeneration. The aim of this study is to assess whether graphene and related nanomaterials can be useful in the fabrication of such conduits. A comparison is made between graphene oxide (GO) and reduced GO substrates. Our results show that the graphene substrates are highly biocompatible, and the reduced GO substrates are more effective in increasing the gene expression of the biomolecules involved in the regeneration process compared to the other substrates studied.
迫切需要改善周围神经损伤的临床治疗效果。许多努力都致力于生物工程导管的制造,这种导管可以将干细胞输送到损伤部位,以促进和引导周围神经再生。本研究的目的是评估石墨烯及相关纳米材料是否可用于制造此类导管。对氧化石墨烯(GO)和还原氧化石墨烯基底进行了比较。我们的结果表明,石墨烯基底具有高度的生物相容性,与其他研究的基底相比,还原氧化石墨烯基底在增加参与再生过程的生物分子的基因表达方面更有效。
