Elevation of a potassium current in differentiating human leukemic (HL-60) cells.


Human promyelocytic leukemia (HL-60) cells display a novel voltage-dependent outward current under voltage clamp. This current is present at low levels in the proliferative state and in granulocytes derived from HL-60 cells which were induced to differentiate with retinoic acid. It is elevated in macrophages derived from HL-60 cells after exposure to… (More)
