Abstract

The vesicular cells (Blasenzellen) are characterized by numerous vesicles produced by the cell membrane. They appear in two different functional states: a) as cells, which contain a high amount of glycogen but only few membranes of the smooth-surfaced endoplasmic reticulum and b) as cells, which contain little or no glycogen at all but a good developed smooth-surfaced endoplasmic reticulum.Ramified fibrocytes show numerous invaginations of the plasmalemma. The material closing the cell from outside, is found inside the invaginations. At a distance from the cell surface there are typical parallel collagen fibres.The granules of the granulated cells (Körnchenzellen) are surrounded by membranes and show a concentrical layering.The branching melanocytes contain pigment granules which also are enclosed in membranes and which are not of homogenous structure. In a matrix of lower density there lies the dense core with its irregular pale central part.
