Figure 5. Transmission electron microscopy
of caveolae in HLE-B3 cells treated with high concentrations of
glucose. Cells were seeded on glass coverslips, treated with 5 mM or 25
mM glucose for 48 h, fixed with glutaraldehyde, post-fixed with osmium
tetroxide, and stained with uranyl acetate and lead citrate. A:
5 mM glucose-treated (control) cells. Arrows point to caveolae. B:
25 mM glucose-treated cells.
