Studies on the structure of the Golgi apparatus. II. Liver cells of Rhacophorus maculatus gray

Abstract

It is suggested that the chromophobic or idiosomic component of vertebrate somatic cells occurs as a core in the Golgi substance. In the liver cells of Rhacophorus during activity, the core which is masked in the early stages becomes differentiated inside the substance of the apparatus in various regions. Rupture and disintegration of the apparatus takes place in those regions where chromophobic areas have been differentiated resulting in the formation of osmophil masses which have no visible chromophobic component. The demonstration of a chromophobic or idiosomic component in the vertebrate Golgi apparatus renders the comparision of secretion of various substances by the apparatus in vertebrates and invertebrates more logical.
