Adipose tissue is abundant in this specimen of mesentery that also includes several lymph nodes.
White adipocytes are large, round cells (up to a 100 µm diameter) with a single droplet of lipids (unilocular). A thin rim of cytoplasm encircles the droplet with the nucleus flattened along the edge of the cell.
Most cells and their nuclei are seen in cross section. Infrequently, the nuclei are seen en face.
The cells appear empty because the lipids are extracted during tissue preparation.
