MORPHOLOGICAL AND CYTOCHEMICAL IDENTIFICATION OF THE GOLGI APPARATUS

Morphological and Cytochemical Identification of the Golgi Apparatus

1. A modification of Elftman's direct silver method reveals both the lipochondria of Baker and the network of Golgi in the same cell. For purpose of distinction, it is proposed to call Baker's lipochondria the nucleopetal fraction, the Golgi network the nucleofugal fraction of the Golgi apparatus. 2. The nucleopetal fraction is located closer to the nucleus. It is spherical in shape and appears...

Cytochemical Staining of the Golgi Apparatus in Amoeba Proteus

The Golgi apparatus has been shown to be involved in the packaging of secretory proteins (Caro and Palade, 1964 ; Jamieson and Palace 1967 a, 1967 b), and in the production of acid mucopolysaccharides and glycoproteins (Neutra and Leblond, 1966 ; Berlin, 1967 ; Thiéry, 1967 ; Rambourg et al, 1969; Whur et al., 1969) . Other suggested functions of the Golgi apparatus include the formation of the...

A cytochemical study of the neuronal Golgi apparatus. Experimental diphtheritic encephalitis in rats.

Cytochemical studies on golgi apparatus, GERL, and lysosomes in neurons of dorsal root ganglia in mice.

Cytochemically demonstrable thiamine pyrophosphatase activity is present in the innermost Golgi element in both small and large neurons of the dorsal root ganglia in CF1, C57 black, and C57 beige mice, thus resembling the neurons of rat dorsal root ganglia. The localization of acid phosphatase (EC 3.1.3.2) activity in the large neurons of dorsal root ganglia in these mice is also similar to tha...

Positioning the Golgi Apparatus

Ríos et al. (2004) report in this issue that the Golgi protein GMAP-210 is sufficient to confer pericentrosomal positioning and recruits gamma-tubulin and associated microtubule-nucleating ring complex proteins to Golgi membranes. The results raise the possibility that short microtubules emanate from the Golgi to mediate its organization and positioning.
