Which combination correctly identifies the tissue and staining used in the slide?

• A. Adipose Tissue with Osmium Tetroxide
• B. Bone Tissue with Wright Stain
• C. Adipose Tissue with Wright Stain
• D. Bone Tissue with Osmium Tetroxide

Answer: (A)

Stains that target specific tissue components help you identify the tissue type. Osmium tetroxide fixes and stains lipids, turning lipid-rich areas dark, so adipose tissue shows up prominently with a dark, lipid-containing appearance. Adipocytes are filled with lipid droplets, and osmium preserves and colors these lipids, making the tissue easy to recognize. In contrast, Wright stain is designed for differentiating cells in blood and bone marrow and doesn’t highlight the lipid-rich architecture of adipose tissue or the mineralized matrix of bone well. Using osmium tetroxide on bone wouldn’t reveal the mineralized bone structure clearly, since the stain primarily highlights lipids rather than the bone matrix. Therefore, the combination of adipose tissue with osmium tetroxide best matches the slide.
