DU Bing, et al. The impact of rh-LIF on HL-60 cell line[J]. Journal of Chongqing Medical University, 2003,(3):270-272. DOI: 10.13406/j.cnki.cyxb.2003.03.005.
Objective:To investigate the effect and mechanism of rh-LIF on proliferation and differentiation of HL-60 cell line.Methods:HL-60 cells were treated with different dosage of rh-LIF for 3 to 6 days
cell cycle was analysed by flow cytometry
expression of P53 and P21 protein were observed by immunohistochemistry and P53 mRNA were assayed by in situ hybridization.Results:HL-60 cell line could differentiate into monocyte and macrophage cell line in the presence of rh-LIF.The proliferation of HL-60 cells were inhibited in the presence of rh-LIF
the cells stagnated at G 1 stage
while expression of P53
P21 protein and P53 mRNA were increased obviously.Conclusion:The effects of rh-LIF on the proliferation and differentiation of HL-60 cells may be associated with the increase of P53
