扫描电子显微镜(SEM)观察体外培养的细胞,能得到细胞表面形态的信息,起到透射电镜(TEM)无法起到的作用。因此,它的应用,更加完善了对细胞超微结构的研究。有关SEM对培养的人星形细胞瘤观察的资料,国内未见发表,国外报道也不多。近年来,我们在这方面进行了一些探索,现报告如下。 Scanning electron microscopy (SEM) observed in vitro cultured cells, cells can get the surface morphology information, the transmission electron microscopy (TEM) can not play a role. Therefore, its application, more perfect cell ultrastructure research. SEM on cultured human astrocytoma observed data, no domestic published, not many foreign reports. In recent years, we have conducted some explorations in this regard. We hereby report the following.
