Adipose tissue morphology.

<p>(A) Representative images of epididymal adipose tissue stained with anti-F4/80 antibody (upper panel; the arrows indicate F4/80-positive cells) and H&E (lower panel) in <i>db/db</i> mice administered EP4 agonist (right column) or vehicle (left column). Scale bars: 100 μm. (B) Percent of F4/80⁺ CLS areas in mouse epididymal adipose tissue (n = 7 each). (C) Quantification of adipocyte size (n = 7 each). All values are mean ± SEM. ♯ p<0.01 vs. vehicle. CLS, crown-like structures.
