Fig. 8From: Development of in vitro gene delivery system using ORMOSIL nanoparticle: Analysis of p53 gene expression in cultured breast cancer cell (MCF-7)Transmission electron microscopic analysis of ORMOSIL nanoparticles transfection at cellular level. a The ORMOSILNs are mainly distributed in the cytoplasm of MCF-7. The arrow indicates the ORMOSILNs. b Non-transfected cells (control). c ORMOSILNs distribute in the cytoplasm at ×100,000 magnification. The arrow indicates the ORMOSILNs in different sizes. d Non-transfected cells at ×100,000 magnification (control)Back to article page
