Adipocyte
A small accumulation of adipocytes is seen here in a loose connective tissue. This tissue has been fixed with osmium tetroxide, which preserves the large lipid droplet and prevents it from being extracted during tissue preparation. The reaction of osmium with the lipid produces the brown-black staining. 1000x
