1 Amelioration of azidothymidine-induced erythroid toxicity by hemin and stem cell factor in immune-suppressed mice. Zidovudine kit ligand Mus musculus
2 We reasoned that hemin, previously shown to both enhance BFU-E proliferation and accelerate erythroid maturation, might bring about differentiation of this large SCF-induced pool of BFU-E and further protect BFU-E from AZT"s toxic effect. Zidovudine kit ligand Mus musculus
3 50 microM hemin increased the ED50 of AZT from 1 x 10(-7) M to 1.7 x 10(-6) M. SCF also ameliorated AZT-induced toxicity, but to a lesser extent. Zidovudine kit ligand Mus musculus
4 50 microM hemin increased the ED50 of AZT from 1 x 10(-7) M to 1.7 x 10(-6) M. SCF also ameliorated AZT-induced toxicity, but to a lesser extent. Zidovudine kit ligand Mus musculus
5 SCF and hemin increased the number of BFU-E colonies observed in the presence of AZT in an additive fashion. Zidovudine kit ligand Mus musculus
6 The resistance of BFU-E to AZT"s cytotoxic effect was greater in cultures receiving hemin and SCF together than in cultures receiving SCF or hemin alone. Zidovudine kit ligand Mus musculus
7 The resistance of BFU-E to AZT"s cytotoxic effect was greater in cultures receiving hemin and SCF together than in cultures receiving SCF or hemin alone. Zidovudine kit ligand Mus musculus
8 Combinations of SCF and hemin may prove useful in ameliorating AZT toxicity in both immune-suppressed mice and human immunodeficiency virus (HIV)-infected patients. Zidovudine kit ligand Mus musculus
