Because the translation rate is an important determinant of cell proliferation , we have investigated translation initiation during human myeloid cell differentiation using the HL-60 promyelocytic leukemia cell line and the U-937 monoblastic cell line .
 ( cell line: U-937 monoblastic cell line, None) , ( cell type: human myeloid cell, None) , ( cell line: HL-60 promyelocytic leukemia cell line, None)
