Summary
Polygonal crystalline structures were found in the lysosomes of human ependymoma cells, well demarcated from the granular matrix of the lysosomes. They were composed of a regular spacing at an interval of 150–160 Å of alternating dense and less dense layers, orientated along one to three axes and forming rectilinear, tetragonal, or hexagonal arrays.

Ependymoma Polygonal Crystalline Structures Electron MicroscopyZusammenfassung
Polygonale kristalline Strukturen fanden sich in Lysosomen der Zellen eines menschlichen Ependymoms. Die von der granulären Matrix der Lysosomen gut abgegrenzten Strukturen waren aus regelrecht in Abständen von 150–160 Å angeordneten Formationen aufgebaut, in denen dichte und weniger dichte Schichten abwechselten. Diese waren in einer der drei Achsen angeordnet und bildeten rechteckige, tetragonale oder hexagonale Gebilde.
