It is impossible always to identify unambiguously the form and extent of the above-mentioned zones in each case, as the criteria useful for the identification of each cellular zone are imprecise.
However one of us was able to demonstrate the feline pNr as consisting of a long cellular zone continuing from the ND to the rostral part of the mNr through the use of an HRP-tracing method (Onodera, 1984 [3]).
(2) Cellular zone, which is composed of invading Schwann cells.
In this species, the pallium shows throughout development a thin, very compact periventricular cellular zone.
The presence of peripheral rich cellular zone and tissue edema may contribute to high density during enhanced scanning.
Microvessel density was qualitatively assessed by examining the entire vital cellular zone of the tumours with a light microscope at 100× magnification.
Gouty tophi consist of foreign body granulomas composed of mono- and multinucleated macrophages surrounding deposited MSU crystals: the central zone bears MSU crystals, and is surrounded by the corona, a cellular zone of macrophages, mast cells, and plasma cells.
In particular, the characteristic ECM subzone cellular zone 3 (CZ3) becomes apparent; CZ3 consists of coherent fibrous material that creates honeycomb-like chambers at a significant distance around individual cells.
