Figure 9. Endocytosis of 293T-Exo by retinal neurons and RGCs. Ischemia injury promoted endocytosis of 293T-Exo by retinal neurons and RGCs. The nuclei were stained with DAPI (blue), 293T-Exo was stained with fluorescent-tag (green), retinal neurons were stained with Beta III tubulin (red), and the nuclei of RGCs were stained with BRN3A (magenta). Scale bar = 25 μm.
