Fine structural studies on cultured human glial and glioma cells: techniques and applications.

Transmission electron microscopy (TEM), scanning TEM, and scanning electron microscopy in combination with special culture techniques and ordinary cell biologic methods were used to study several problems in cellular pathology and tumor biology. The human glial and glioma cell system is also discussed. The cell system and ultrastructural techniques described may be used in many other areas of study and may be relevant in future investigations of cell pathology.
