1898: The Golgi apparatus emerges from nerve cells

A century ago, Camillo Golgi discovered in neurons an intracellular network of anastomosing threads, impregnated by the chromoargentic reaction he had devised to stain the nervous tissue, This structure, designated by Golgi as 'internal reticular apparatus', was soon detected in a wide variety of eukaryotic cells. However, skepticism arose on the existence of the Golgi apparatus in the first decades of this century, when it was fiercely debated whether this structure represented a genuine new cell constituent or an artifact due to the deposit of metallic impregnation on diverse cytoplasmic structures,The reality of the Golgi apparatus became established unequivocally only with the application of electron microscopy; with the visualization of its fine structure, the apparatus finally achieved the status of cytoplasmic organelle,and thus, linked with Golgi's name, entered the modern era of investigation on its components, chemistry and function.
