Retrovirus mediated gene transfection was carried out. First, the package cell line PT67 was transfected by lipofectAMINE TM2000, so as to obtain recombinant retrovirus supernatant, which was directly used in the transfection of MSCs.

• 反转录病毒介导的基因转染,首先利用LipofectAMINETM 2000转染包装细胞系PT67,获得重组反转录病毒上清,然后用病毒上清直接感染骨髓间充质干细胞。
