These are unilocular—i.e., their cytoplasm contains a single humongous lipid-rich vacuole containing triglycerides and cholesteryl ester that flattens the remaining cytoplasm and nucleus to the outer edge. White fat cells—all 30 billion of them—secrete adiponectin, leptin and resistin, and weigh 13 kg/2 stone/30 lbs. White adipocytes divide once they grow beyond 4 times their usual size. (2) Brown (baby) fat cells are multilocular and polygonal. In contrast to white fat cells, brown fat cells are rich in mitochondria and generate heat. fat cell(fat sel)Synonym(s): adipocyte, adipose cell. adipocyteA fat cell. A cell that synthesizes and stores neutral fats (triacylglycerols or TRIGLYCERIDES). Human fat is a liquid at body temperature, so adipocytes are normally filled with oil. Adipocytes develop from adipoblasts, which derive from fibroblasts. |
