(a) Optical imaging of DiD-labeled cells immediately after labeling. First 3 rows: triplicately labeled cells. (Top row: 4 million/cells mL; Second row: 2 million cells/mL; Third row: 1 million cells/mL). Fourth row: unlabeled cells (2 million cells/mL). Fifth row: DMEM alone. (b) Ratio of fluorescence of cells to media (Y-Axis) for each sample of cells (X-Axis). The ratio of labeled cells to media was significantly higher at all concentrations than the ratio of unlabeled cells to media (p < 0.01). Error bars represent standard error of the mean.
