骨髓基质细胞是造血微环境中的重要组成部分。我们借助逆转录病毒载体将小鼠白细胞介素 3(IL 3)cDNA导入小鼠骨髓基质细胞 ,利用聚合酶链反应 (PCR)检测基质细胞是否导入外源性IL 3基因 ,并观察其对造血细胞增殖活性的影响。材料和方法1 材料 逆转录病毒载体pL
Bone marrow stromal cells are an important part of the hematopoietic microenvironment. We introduced murine interleukin 3 (IL 3) cDNA into mouse bone marrow stromal cells by retroviral vector and detected whether stromal cells imported exogenous IL 3 gene by polymerase chain reaction (PCR) and observed its effect on hematopoietic Effect of Cell Proliferation Activity.
