摘要: 为了改进髓系细胞系的制备方法,采用Tet-On诱导型逆转录病毒载体,通过添加Doxycycline以诱导MLL-AF9融合基因在成年骨髓的血液祖细胞/干细胞中表达,获得髓系细胞系。本研究发现永生化小鼠髓系细胞系的制备方法,通过条件性表达MLL-AF9获得的永生化的髓系细胞系和成年小鼠骨髓中的原代髓系细胞相比,具有相似的表面标志物,即CD11b+,但永生化的髓系细胞系极易扩增,获得大量均一的细胞群体。

Abstract: In this study,an immortalized mouse myeloid cell line was prepared.The Tet-On inducible retrovirus vector was used to induce the expression of MLL-AF9 fusion gene in hematopoietic progenitor cells/stem cells of adult bone marrow by adding Doxycycline to obtain a myeloid cell line.This study found that immortalized mouse myeloid cell line preparation methods,through the conditional expression of MLL-AF9 obtained immortalized myeloid cell lines compared with the primary myeloid cells in adult mouse bone marrow,have a similar surface The marker,ie,CD11b+,but immortalized myeloid cell line is easily amplified,obtaining a large number of uniform cell populations.

Key words: Myeloid cell line, virus, Preparation, Doxycycline
