Mechanism for fetal hemoglobin induction by hydroxyurea in sickle cell erythroid progenitors.

abstract：:In addition to transferrin, ferritin can also function as a source of iron for heme synthesis (Gelvin D, et al. Blood 1996;88:3200-3207; Meyron-Holtz EG, et al. Blood 1999;94:3205-3211). In the present study we investigate the effect of external ferritin on the proliferation and hemoglobinization of human erythroid pr...
