Figure 2.
Time-dependent cellular uptake of Gd-DO3A, Gd-Hexyl-DO3A, and ProGlo in PR(+) T47D human breast cancer cells (top) and PR(-) MDA-MB-231 human breast cancer cells (bottom). Cellular uptake of ProGlo was significantly higher than Gd-Hexyl-DO3A and Gd-DO3A in both cell lines (Student's t test, p < 0.05). Data are mean ± standard deviation.
