adipocyte(redirected from Preadipocytes)
Also found in: Dictionary, Encyclopedia.
a connective tissue cell distended with one or more fat globules, the cytoplasm usually being compressed into a thin envelope, with the nucleus at one point in the periphery.
adipocyte/ad·i·po·cyte/ (-sīt″) fat cell.
See fat cell.
a fat (adipose) cell, potentially containing a large fat vacuole consisting mainly of triglycerides.
AdipocyteA generic term for any fat-storing cell, either:
(1) White (yellow, or adult) fat cells, which are far more common. 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)
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.
a cell specialized for the storage of fat; the fat is stored in a large cytoplasmic vesicle.
