Confocal fluorescence images of VK and Endo cells with coumarin-6 encapsulated PLGA/S-100 50%/50% NP (C-6 NP) after 4 hr incubation and control. An overlay of red and green channels is shown. (A) Z-stacking of X–Y projection of VK cells treated with C-6 NP. (B) Z-stacking of X–Y projection of Endo cells treated with C-6 NP. (C) Y–Z projection of the optical section of the VK cells incubated with C-6 NP. (D) Y–Z projection of the Endo cells incubated with C-6 NP. (E) Z- stacking of X–Y projection of control VK cells treated with medium alone. (F) Z-stacking of X–Y projection of control Endo cells treated with medium alone.
