基因转移是用物理的、化学的、或生物的手段将外源基因导入受体细胞并使之表达的一种技术。80年代后,哺乳动物细胞基因转移技术相继问世,日臻完善,得到了广泛的应用,推动了生命科学研究的发展。哺乳动物细胞基因转移包括3个阶段(?)基因转移前的准备;外源基因的导入;基因转移后的表达。 Gene transfer is the use of physical, chemical, or biological means to foreign genes into recipient cells and expression of a technology. After the 1980s, mammalian cell gene transfer technology has come out one after another, getting better, has been widely used, and promote the development of life science research. Mammalian cell gene transfer includes 3 stages (?) Pre-gene transfer preparation; introduction of exogenous gene; post-gene transfer.
