Abstract:
This study was purposed to establish and identify the model of extramedullary infiltration of CML-NOD/SCID mice. 24 mice were irradiated with 270 cGy of (137)Cs and absorbed dose rate 80 cGy/min, and were randomly divided into test group I, test group II and control group. The mice in test group I and test group II were injected with 5×10(6) and 1×10(7) K562 cells per mouse respectively, the mice in control group were injected with 0.2 ml of normal saline. The general situation and survival time of these mice were monitored, the extramedullary infiltration of leukemia cells was detected by histopathology examination and RT-PCR. The results indicated that at 4 - 8 weeks after injection, all the mice of group I and group II displayed extramedullary infiltration, suggesting that CML/NOD-SCID model was successfully established. It is concluded that the model of extramedullary infiltration of CML/NOD-SCID mice can be established by injection K562 cells into caudal vein, and can be confirmed by histopathologic examination and detection of BCR-ABL fusion gene using RT-PCR.
