Predominant expression of σ and ε globin genes in human leukemia K-562(S6) variant cell line

Abstract
In the human leukemia K-562(S6) cell line (a) the accumulation ofa-globin chains is low or absent, (b) ζ-globin gene expression is correlated with expression of ε-chains and (c) the genes responsible for the terminal cell division are not operated within 8–12 cell cycles, while K-562 (S6) cells are fully induced to erythroid differentiation.
