With the aim of identifying genetic targets for these transcription factors, we stably transfected cDNAs encoding EBF or a covalent homodimer of E47 , individually or together, into immature hematopoietic Ba/F3 cells , which lack both factors.
 ( protein: E47, None) , ( protein: EBF, None) , ( cell line: immature hematopoietic Ba/F3 cells, None) , ( DNA: transfected cDNAs, None)
