Diagnostic Electron Microscopy Service

The electron microscope (EM) is used as an important analytical method in the physical, chemical and biological sciences. Compared with light microscope, scanning electron microscopy (SEM) and transmission electron microscope (TEM) use electrons to image tissues at much greater magnification, so EM becomes an essential diagnostic tool to screen human tissues at high magnification and allows for visualization of details within cells. As a powerful tool for visualizing the tissues, cells, virus, nanomaterials as well as other biopsy, TEM is particularly important in tumor pathology, neuropathology, kidney disease, and so on.

When combined with other methods, such as immunohistochemical and molecular genetic techniques, EM exhibits even greater impact on sample analysis and visualization, especially for understanding the relationships of the structure and function at the subcellular level. For example, light microscopy and immunofluorescence techniques are not able to provide confident result in the diagnosis of ependymoma due to that not all ependymomas are immunoreactive to epithelial membrane antigen (Figure 1A). EM, on the other hand, delivers ultrastructure of tissues and shows a well-developed cellular junctions, such as desmosomes, microvilli, and cilia, thereby allowing for direct diagnosis of ependymoma (Figure 1B).
