The adrenal capsule, the entire adrenal cortex and adrenal medulla were PAS-positive (Figs.
The histological features of the adipose tissue surrounding the adrenal capsule of the African giant rat are similar to those of other mammals (Bacha & Bacha, 2000).
The positive reactions of the adrenal capsule of the African giant rat with Masson's Trichrome, Periodic Acid Schiff and Verhoeff stain imply that the capsule is rich in collagen, carbohydrate and elastic fibers, respectively.
The "width" (length of APCCs along the adrenal capsule) and "depth" (distance from the capsule end to the farthest point in a vertical direction) of each APCC were calculated from measurements on the printouts.
Cell lineage analyses using genetically engineered mice have shown that some progenitor cells in the adrenal capsule generate ZG cells , which develop further into ZF cells .
The double-negative zone in rats is physically fragile, and the capsular portion (adrenal capsule and ZG) may be separated from the inner adrenal zones (ZF, ZR, and medulla) manually along the double-negative zone.
