The relative sensitivity of peripheral blood T-lymphocyte colony forming cells and bone marrow CFU-GM to
Leukemia Research
|January 1, 1985
Abstract:
The effects of the nucleoside deoxyadenosine (AdR) towards 2'deoxycoformycin (dCF) treated peripheral blood T-lymphocyte and bone marrow myeloid progenitor cells has been studied. Mononuclear cell preparations were exposed to dCF and AdR in suspension culture prior to washing and culture in a medium free of exogenous nucleosides. The combination of dCF and AdR was found to be highly toxic to peripheral blood T lymphocyte colony forming cells (CFU-TL) following prolonged (18 h) incubation. CFU-GM were markedly less sensitive to the combination of dCF and AdR, concentrations of dCF (10(-5) M) and AdR (10(-5) M) which produced an almost total inhibition of CFU-TL only inhibited CFU-GM by a mean of 10%.
