Figure 1. Representative phase-contrast images of confluent passage 3 human corneal endothelial cells cultured from a 14-year-old donor and a 69-year-old donor. HCEC from these donors were among those used for subsequent proteomic analysis. Cells cultured from older donors were consistently larger and displayed more variable shapes than cells from young donors. Original magnification: 4X.
