Abstract:
Thanks to the works of Rudolph Virchow, a great German scientist, one of the founders of
modern pathological anatomy, today there are no diseases whose knowledge is not based on the
morphological study of cells – the structural units of living organisms. However, it was possible to
see the normal cell structure in all its modifications only in the second half of this century thanks to
the application of the ultrastructural method of studying cells using transmission (transparent) and
scanning electron microscopy, electronic histo- and immunohistochemistry, and electronic
autoradiography.
