Graphene oxide (GO) has received increasing attention in bioengineering fields due to its unique biophysical and electrical properties, along with excellent biocompatibility. The application of GO nanoparticles (GO-NPs) to engineer self-renewal and differentiation of human fetal neural stem cells (hfNSCs) is reported. GO-NPs added to hfNSC culture during neurosphere formation substantially promote cell-to-cell and cell-to-matrix interactions in neurospheres. Accordingly, GO-NP-treated hfNSCs show enhanced self-renewal ability and accelerated differentiation compared to untreated cells, indicating the utility of GO in developing stem cell therapies for neurogenesis.
氧化石墨烯（GO）因其独特的生物物理和电学性质以及出色的生物相容性，在生物工程领域受到越来越多的关注。据报道，氧化石墨烯纳米颗粒（GO-NPs）可用于调控人类胎儿神经干细胞（hfNSCs）的自我更新和分化。在神经球形成过程中添加到hfNSC培养物中的GO-NPs可显著促进神经球中细胞间和细胞与基质间的相互作用。因此，与未处理的细胞相比，经GO-NP处理的hfNSCs表现出更强的自我更新能力和更快的分化速度，这表明GO在开发用于神经发生的干细胞疗法中具有实用性。
