几种昆虫细胞表面的扫描电镜观察

THE OBSERVATION OF CELL SURFACE OF SEVERAL INSECT CELLS BY USING SCANNING ELECTRON MICROSCOPY

斜纹夜蛾、草地贪夜蛾及家蚕三种昆虫培养细胞表面的扫描电镜研究揭示:三种细胞表面披有微毛结构,家蚕细胞表面覆盖微毛较斜纹夜蛾与草地贪夜蛾细胞多。家蚕细胞经BmNPV攻毒后,微毛数量增加,微绒毛是昆虫培养细胞表面广泛存在的特化结构。

The paper reports the observation of cell surface of cultured cells from spodoptera litura, spodoptera frugiperda and Bombyx mori by using scanning electron microscores. The study revealed that three insect cells tested were ewveloped with microvillrs on cell surface. Number of microvillus of BmN cells were more than that of SL-1 and sf-9 cells. After challenged with BmNPV number of microvillus on cell surface of Bran cell apperantlly, increased. Therefore we can conclude that there are extensively microvillus on cell surface of cultured insect cells.
