Adipose tissue is loose connective tissue that accumulates in animals and serves primarily for energy storage, insulation, and thermoregulation. It is predominantly composed of adipocytes, but also contains a stromal vascular fraction consisting of preadipocytes, fibroblasts, vascular endothelial cells, and immune cells. Recent research has discovered a dynamic role of adipose tissue in the production and secretion of various hormones and as an active endocrine organ. The excessive accumulation of adipose is known as obesity. Ways to prevent over-accumulation of adipose is a field of intense research. In addition to obesity, adipose tissue has been found to participate in various physiological processes, including reproduction, angiogenesis
