Below, click on the thumbnail image to go to a 300dpi stereo pair version of each figure. At this magnification, all that is apparent is the fantastic density of the amyloid deposit, and its utter foreigness to the brain. The extreme smoothness of these membranes and their utter lack of intra-membrane particles suggest that they represent debris derived from degenerating cells. The same comments apply as in Figure 1. The same comments apply as in Figure 1.
Membranous cell processes trapped within bundles of amyloid fibrils.
The difficulty in identifying such cell processes in these stereo electron micrographs is due partly to the problem of adequately preserving cells embedded in such a dense matrix of foreign protein. The edge of an amyloid deposit, where smooth contours of fractured membranes intercalate with densely packed bundles of amyloid fibrils. Overview of the mixture of bundled fibrils and random membrane profiles found at the heart of an amyloid deposit. The edge of an amyloid deposit, where smooth contours of fractured membranes intercalate with densely packed bundles of amyloid fibrils. The same comments apply as in Figure 5.
