From: Fabrication and characterization of DNA-loaded zein nanospheres
Analysis of sphere internalization within Caco-2 cells, with DiO membrane staining, using merged fluorescence confocal images of entire z-stack with orthogonal views, XZ and YZ (A) and a digital magnification of the area outlined by a white square in A (B). Punctate green staining within cells are indicative of endosomes. Filled arrows indicate internalized, autofluorescent nanospheres. Scale bars in A and B represent 50 and 20 μm, respectively.
