摘要:: HL-60 promyelocytic leukemic cells can differentiate into more mature myeloid cells with the addition of dimethylsulfoxide, butyric acid or retinoic acid and can differentiate into macrophages with the addition of phorbol ester 12-0-tetradecanoylphorbol-13-acetate (TPA). After the addition of an inducer, the HL-60 cell volume shows a daily decrease while the cell number increases at a rate similar to the untreated control cells. Flow cytometry measurements show an increase in G1 cells and a decrease in S cells after day 1. Since the generation time is constant, the data suggest that the length of time spent in the different cell cycle stages has changed during differentiation. Within 3 hours after the addition of TPA to HL-60 cells, selective adhesion of G1 cells occurs. Smaller sized cells are recovered from the flask bottom and larger sized cells are recovered from the supernate. Flow cytometric analysis reveals a G1 and S block in cells obtained from both the supernatant and from the flask bottom. After 1 day of TPA incubation, there is preferential adhesion of G1 and G2 cells with the nonadherent cells being primarily in the S and G2 cell cycle stages and undergoing a cell cycle traverse.
