Many hES cell lines have been established under different conditions in the world. The firstly established hES cell lines were cultured on mouse embryonic fibroblast cells with medium containing many undefined animal components such as fetal bovine serum, which may cause cross-transfection with animal pathogen and mycoplasm.

目前，世界上已经建立了多株hES 细胞系，最早建立的hES 细胞系是生长在小鼠胚胎成纤维(mouse embryonic fibroblast， MEF)细胞上的，培养体系中含血清等动物源性成分，这些成分可能引起动物源性病原体或支原体的污染，从而限制了 hES 细胞的临床应用。

The major mutants included non-nodule mutants (18 lines) which failed to nodulate after inoculated with rhizobia for two weeks, ineffective nodulation mutants (9 lines) which had less uneven and white or transparent nodules, an abnormal leaf and flower mutant which was dwarf without stipules, abnormal flowers and less nodules, and a slender mutant with a thin stem and smaller leaves.

While AcMNPV and BmNPV had no stimulatory effect in nonsensitive cell lines BmNPV hr3 has been demonstrated to increase the transcriptional activity of cislinked hel510 promoter. In this study, Sf-21, Bm-N and Hi-5 cell lines were transfected with pBmhel510luc-hr3down, and then were infected with each of AcMNPV, BmNPV and HyNPV. The results indicated that viral factors could interact with hr3 to significantly copromote the transcriptional level of hel510 promoter.

BmNPV hr3已被证明具有增强子功能，将hr3与hel510启动子顺式连接的质粒pBmhel510luc-hr3down转染Sf-21、Bm-N和Hi-5细胞后，再用上述三种病毒分别感染每一种细胞，hel510启动子的转录活性得到显著提高，表明病毒因子能够识别hr3，二者通过相互作用，共同增强解旋酶基因启动子的转录水平。
