Recently, as novel nanomaterials with outstanding physicochemical properties, boron nitride nanospheres (BNs) have emerged as a promising candidate for drug delivery. However, poor dispersity and lack of tumor targeting severely limit further applications. In this study, cancer cell–membrane biomimetic BNs were designed for targeted anticancer drug delivery.Methods: Cell membrane extracted from HeLa cells (HM) was used to encapsulate BNs by physical extrusion. Doxorubicin (Dox) was loaded onto HM-BNs as a model drug.Results: The cell-membrane coating endowed the BNs with excellent dispersibility and cytocompatibility. The drug-release profile showed that the Dox@HM-BNs responded to acid pH, resulting in rapid Dox release. Enhanced cellular uptake of Dox@HM-BNs by HeLa cells was revealed because of the homologous targeting of cancer-cell membranes. CCK8 and live/dead assays showed that Dox@HM-BNs had stronger cytotoxicity against HeLa cells, due to self-selective cellular uptake. Finally, antitumor investigation using the HeLa tumor model demonstrated that Dox@HM-BNs possessed much more efficient tumor inhibition than free Dox or Dox@BNs.Conclusion: These findings indicate that the newly developed HM-BNs are promising as an efficient tumor-selective drug-delivery vehicle for tumor therapy.Keywords: boron nitride nanospheres, cancer-cell membrane, targeted drug delivery, chemotherapy, biomimeticFeng SRen YLi HTang YYan JShen ZZhang HChen FDove Medical Pressarticleboron nitride nanospherescancer cell membranetargeted drug deliverychemotherapybiomimeticMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 16, Pp 2123-2136 (2021) |
