MODEL FOR HEMATOPOIETIC CELL GROWTH, DIFFERENTIATION AND DISEASE

摘要

The invention is a genetic construct comprising the coding sequence for a hormone dependent E2a-Pbx1 protein. The invention is the use of the construct to generate hematopoietic cell lines arrested in differentiation upon exposure to the appropriate hormone. Upon removal of the hormone, cells undergo normal, synchronous differentiation providing a system for the study of normal differentiation. Expression of a number of oncogenes in the cells maintains the cells in an undifferentiated state, providing a model for the study the mechanisms of leukemia, and for the testing of pharmacological agents for the treatment and amelioration of the disease.
