Electron Microscopy in Pathology

Electron Microscopy (EM) provides ultra-structural visualization of tissues and cells, far beyond the resolution of light microscopy, and is an essential topic in advanced cellular pathology. This module covers the theoretical aspects and instrumentation of both Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM), highlighting their differences and applications. It details the rigorous specimen preparation process, including fixation with aldehydes and osmium tetroxide, dehydration, embedding in epoxy resins, ultramicrotomy, and staining with heavy metals like uranyl acetate and lead citrate. For Zambian tertiary students in degree and diploma programs in biomedical sciences or histopathology, understanding EM is key to diagnosing challenging cases such as renal diseases, certain tumors, and muscle disorders. This knowledge enhances analytical skills, supports research projects, and prepares learners for specialized roles in diagnostic electron microscopy units, contributing to the advancement of pathology services in Zambian universities and teaching hospitals.
