The Establishment and Identification of Acute Myeloid Leukemia NOD-SCID-IL2rg-/-Mice Model by Using Luciferase-Expressing KG1a Cells
OBJECTIVE: To establish the in vivo traceable acute myeloid leukemia mice model with Luciferase-Expressing KG1a Cells.
METHODS: KG1a cells with stable luciferase gene expression (called as KG1a-Luc cells) were constructed by lentivirus transfection, then sifted out by puromycin. Eighteen male NOD-SCID-IL2rg-/-mice aged 8 to 12 weeks were randomly and equally divided into two groups: the control group and the KG1a-Luc group. The mice in KG1a-Luc group were injected with 200 μl PBS containing 5×106 KG1a-Luc cells through tail veins, and the mice in control group were injected with 200 μl PBS only. The bioluminescence imaging technology was used to monitor the tumor burden in vivo. The peripheral blood of the mice in both groups was analyzed by flow cytometry. After the mice were sacrificed, there were pathologic evaluations: bone marrow and spleens made into smears, and livers sliced to get paraffin sections. The survival time of the mice in the two groups was recorded and compared.
RESULTS: KG1a cells expressing luciferase stably were successfully obtained. The tumor luminescence wildly spread at day 17 captured by in vivo imaging. The KG1a-Luc tumor cells could be detected in the peripheral blood of the mice, with the average percentage of (16.27±6.66)%. The morphology and pathology result showed that KG1a-Luc cells infiltrate was detected in bone marrow, spleens and livers. The survival time of the KG1a-Luc mice was notably shorter as compared with those in the control group, the median survival time was 30.5 days (95%CI: 0.008-0.260).
CONCLUSION: The acute myeloid leukemia NOD-SCID-IL2rg-/-mouse model was successfully established by tail vein injection of 5×106 KG1a-Luc cells.
