Brown adipose tissue (BAT) or brown fat makes up the adipose organ together with white adipose tissue (or white fat). [1] Brown adipose tissue is found in almost all mammals. Classification of brown fat refers to two distinct cell populations with similar functions.
Adipose tissue (also known as body fat or simply fat) is a loose connective tissue composed mostly of adipocytes. [ 1 ] [ 2 ] It also contains the stromal vascular fraction ( SVF ) of cells including preadipocytes , fibroblasts , vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages .
A brown fat cell. Yellow adipose tissue in paraffin. White fat cells contain a single large lipid droplet surrounded by a layer of cytoplasm, and are known as unilocular. The nucleus is flattened and pushed to the periphery. A typical fat cell is 0.1 mm in diameter [2] with some being twice that
Brown fat, which is also called brown adipose tissue, is often referred to as the "good" fat because it helps to burn rather than store calories. It is typically found in areas around the neck and ...
A kind of memory of obesity may be retained by fat tissues even after weight loss, increasing the chance of some people regaining it, a new study suggests.. The research, published in the journal ...
The activity of PRDM16 in white adipose tissue leads to the production of brown fat-like adipocytes within white adipose tissue, called beige cells (also called brite cells). These beige cells have a brown adipose tissue-like phenotype and actions, including thermogenic processes seen in BAT. [7]
A new study in mice looks at how activating healthy brown fat could help promote weight loss and protect against obesity.
