Fat cells. Coloured scanning electron micrograph (SEM) of a group of fat cells, or adipocytes, in human skin. Adipocytes together form adipose fat tissue. Stored fat accumulates as lipid droplets in these cells; lipids concentrate and fuse to form a single large droplet, displacing the cell nucleus to one side and reducing the cytoplasm to a thin rim around the cell periphery. Adipose tissue is associated with connective tissue and forms a thick layer under the skin. It also forms around the buttocks, thighs, and kidneys. It functions as an insulating layer and as an energy store. Magnification: x260 at 35mm size.
