Figure 3. — Transmission electron microscopy showing ultrastructural characteristics of trachea in lean and obese Zucker rats. Amorphous material is present in lamina propria of obese Zucker rats (A-C). Dense deposits are present in microvascular structure in lean (D) and obese (G) Zucker rats. The dense deposit in (G) is shown at higher magnification in (H). Lipid droplets are visible in hyaline cartilage of lean (E, F) and obese (I) Zucker rats. bv, blood vessel; cf, collagen fibers; dd, dense deposit; hc, hyaline cartilage; ld, lipid droplet; lp, lamina propria.
