Impaired G-CSF–induced mobilization in Vdr^−/− mice. G-CSF–induced mobilization. Peripheral blood leukocyte count (A) and CFU-Cs (B) in mice fed with a normal diet (n = 4-7), and leukocyte count (C) and CFU-Cs (D) in mice fed with a high-calcium diet (n = 7-9). Percent of CD45.2 in the competitive reconstitution of mobilized blood (E) and calculated RU at 6 months (F) in mice fed with a normal diet (n = 5), and mobilized blood (G) and calculated RU at 6 months (H) in mice fed with a high-calcium diet (n = 6). *P < .05; **P < .01; ***P < .001.
