Figure 5. Relative gene expression of retinal cell markers. The bar graphs represent relative expression of neural retinal cell markers (CRABPΙ, RHO, PKCα and Thy-1) and neural progenitor/stem cell markers (PAX6, SOX2, VSX2, and Nestin) in HAF, FBS, and DMEM/F12–treated cultures on A/G substrate compared to polystyrene. Each bar represents the mean ± SEM of at least 3 independent experiments in at least triplicate.
