Effects of other nucleosides on the growth of monocytoid (U937, THP-1), K562 erythroid, or HL-60 myeloid cell lines treated with dCF and dAd. Cells were cultured with various concentrations of dCF in the presence of 0 (▪), 10 μmol/L dAd (•), 10 μmol/L each of dC + dG + dT (▴), or 10 μmol/L each of dAd + dC + dG + dT (⧫) for 4 days.
