Abstract: AIM: To explore a method to develop a stable and repeatable murine model of acute promyelocytic leukemia(APL),which progression could be observed.METHODS: For the model, Nod/SCID mice were irradiated by 60Co γ ray and the level of leukocytes was very low at the fifth day, then Nod/SCID mice were injected with HL60 cells intravenously via tail vein.The percentage of HL60 cells in the peripheral blood was determined by flow cytometry, which was used to observe the distribution change of HL60 cells in the peripheral blood.The development of solid tumors in the superficial parts of body was observed daily, and to confirm the characteristics of tumor spread in the mice with histopathological methods.RESULTS: Day 7 post injection, HL60 cells could be detected in the peripheral blood of Nod/SCID mice. About day 30 post injection, solid tumors were observed through the whole body of mice. About day 40, mouse physical fitness began to decline, and mice began to die.The leukemic infiltration was found in the hematopoietic system and non-hematopoietic system. The results of two trials were coincidence.CONCLUSION: For the model, Nod/SCID mice were irradiated by γ ray from 60Co, injected with HL60 cells intravenously via tail vein in the day 5 post irradiation. The course of disease could be kept in about 40 days, and leukemic progression in the Nod/SCID mice with APL was similar with clinical leukemic progression.The model could be used for anti-leukemia drug screening and pharmacodynamic evaluation of candidate drugs with low bone marrow toxicity.
