These cells primarily function as reserves for energy due to their ability to store lipids, particularly triglycerides, efficiently. Subcutaneous fat cells make up the most significant part of the adipose tissue, which provides insulation, cushioning, and serves as an energy reserve for individuals. The location of these cells varies with gender; typically, in males these cells are found in the area of the abdomen, whereas, in females, they are found in the thighs and the buttock region. These cells play an integral role in maintaining metabolic homeostasis. Beyond energy storage, subcutaneous fat cells are also engaged in numerous physiological processes such as maintaining body temperature, protecting the body from mechanical trauma, and functioning as an endocrine organ. They produce and secrete various bioactive molecules known as adipokines which have wide-ranging impacts on various bodily processes, including regulation of appetite, insulin sensitivity, inflammation, and immune function. Subcutaneous fat cells have a characteristic shape, being large, spherical, and filled with a large lipid droplet, unlike other cell types that contain smaller lipid droplets scattered throughout the cytoplasm. The diameter of these cells can range from 30 to over 300 micrometers, significantly larger than most other cells in the body. Of note, these cells also demonstrate a unique property called plasticity. They are able to change their volume dramatically, expanding to store more fat as it is taken up from the bloodstream, and shrinking when fats are released to provide energy.
