the reduced incorporation of 3h-tdr in erythroleukaemia erythroblasts was probably not due to deficiency of the salvage pathway enzyme , thymidine kinase , since mtx ( 10 ( -5 ) m ) which blocks the de novo pathway of thymine-dna synthesis , enhanced the incorporation of 3h-tdr into erythroblasts in erythroleukaemia as well as in normal bone marrows .
