What are HL-60 cells used for in cell biology studies?
The HL- 60 cell line is an immortal human cell line derived from blood lymphocytes from a patient presenting acute promyelocytic leukemia (an aggressive type of leukemia). Advantageously, the HL-60 cell line can be kept in a continuous suspension culture and was one of the first of this cell type for this to be done and characterised. The HL-60 cell line has proven useful in the study of cell formation and differentiation of normal and of course leukemic cells. This is because HL-60 cells can be differentiated through the myeloid pathway to cells such as neutrophils quite easily using DMSO, DMF and other inducers such as retinoic acid.
HL-60 is one of the large number of cell lines that could be selected as being highly useful in cancer research. HL-60 cells can be used for assessing chemotherapy drugs and, when differentiated, can be used as a model for vaccine targets. Other studies of note have used HL-60 cells to look at apoptosis (programmed cell death). In common with many other cell lines discussed in this series, how to culture the cells and having a number of strains or subcultures well characterised makes them easy to work with across the wider scientific community.
