Abstract

A novel system is described, which uses transfection of primary human erythroblasts for the study of gene regulation in differentiating human red cells. This system includes a protocol for liquid culture of erythroid progenitors, which reproduces developmental differences in globin gene expression found between adult and cord blood as well as the maturation-related changes in fetal globin levels observed in adult cells. Reporter constructs driven by globin gene promoters were electroporated into adult and cord blood-derived erythroblasts at different time points during culture. Both the developmental stage and maturation-related differences in endogenous fetal and adult globin gene expression could be reproduced by the transiently transfected reporter constructs. Transfection of primary human erythroblasts during differentiation provides a previously unavailable opportunity to study dynamic aspects of erythropoiesis.
