Our studies showed that levels of C/EBP epsilon mRNA were markedly increased in NB4 cells ( promyelocytic leukemia line ), because they were induced by 9-cis retinoic acid ( 9-cis RA ) to differentiate towards granulocytes .
 cell type: granulocytes; cell line: promyelocytic leukemia line; cell line: NB4 cells; RNA: C/EBP epsilon mRNA
