Figure 6. Uptake of aptamer-Dox conjugate on Müller glial cells addition in vitro. Free Dox, EpDT3-Dox, and Scr-EpDT3-Dox were incubated with Müller glial cells for 2 h and observed under an AxioObserver microscope. A, B, C, and D: 2 h incubated cells unstained, treated with free Dox, Scr-EpDT3-Dox, or EpDT3-Dox. E, F, G, and H: 12 h incubated post 2 h of treatment with free Dox, Scr-EpDT3-Dox, or EpDT3-Dox.
