Medulla (M) of kidney is visualized in lower-left corner of slide (demarcated by dotted line). Surrounding medulla is the cortex (right of dotted line). Within cortex, an arcuate artery (AA) is seen as a white void. Medulla Rays (MR) are linear cellular formations designated by arrows, while renal corpuscles (RC) are seen as circular groups of cells. Note lack of medulla rays and renal corpuscles within medulla, present mainly within the cortex of kidney.
See rat kidney for higher magnification of renal corpuscle.
Large transparent voids show presence of large adipose droplets consistent with Unilocular Adipose Tissue (UAT), while smaller, densly packed voids are indicative of smaller adipose droplets from Multilocular Adipose Tissue (MAT). Right-lower area of slide shows highest density of MAT, while several cells belonging to UAT are visible throughout the slide, with most centralized in the top-left corner.
