Study Notes
Unilocular Adipocyte (White)
- Found in subcutaneous tissue, around blood vessels and kidney.
- Large ovoid or oval in shape.
- Contains a single large fat droplet, pushing the cytoplasm and nucleus peripherally.
- The cytoplasm appears thin and the nucleus flattened when viewed under a light microscope.
- Stains orange with Sudan III stain.
- Electron microscopy reveals large lipid droplets and few cell organelles around the nucleus.
- Responsible for synthesis and storage of fat.
- Provides supporting function, for example around the kidney.
Multilocular Adipocyte (Brown)
- Located in fetuses and newborns.
- Present in adults but in small amounts.
- Smaller than white adipocytes.
- Contains multiple fat droplets within the cytoplasm.
- The nucleus is centrally located and rounded.
- Electron microscopy reveals numerous mitochondria surrounding the fat droplets and few other organelles.
- Primary function is heat generation.
