Cytoprotective Effects of Citicoline and Homotaurine against Glutamate and High Glucose Neurotoxicity in Primary Cultured Retinal Cells

Figure 1

Effects of citicoline and homotaurine on cell viability. MTT assay shows that retinal cells were well preserved in citicoline- or homotaurine-treated cultures, with no evidence of toxicity after treatment at 1, 10, or 100 μM. All data are represented as the mean ± SEM of three independent experiments. CitC: citicoline; Hot: homotaurine.
