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
Its cells contain a single large fat droplet, which forces the nucleus to be squeezed into a thin rim at the periphery. They have receptors for insulin, sex hormones, norepinephrine, and glucocorticoids. White adipose tissue is used for energy storage.
Marrow fat, also known as marrow adipose tissue (MAT), is a poorly understood adipose depot that resides in the bone and is interspersed with hematopoietic cells as well as bony elements. The adipocytes in this depot are derived from mesenchymal stem cells (MSC) which can give rise to fat cells, bone cells as well as other cell types. The fact ...
The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. [1]: 171 It has been found that replication happens in a localised way in the cell nucleus. In the S phase of interphase of the cell cycle; replication takes place.
The classic population of brown fat cells and muscle cells both seem to be derived from the same population of stem cells in the mesoderm, paraxial mesoderm. Both have the intrinsic capacity to activate the myogenic factor 5 (Myf5) promoter, a trait only associated with myocytes and this population of brown fat. Progenitors of traditional white ...
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
In adipocytes, lipid bodies tend to be larger and they may compose the majority of the cell, while in other cells they may only be induced under certain conditions and are considerably smaller in size. Lro1 is a type II integral membrane protein. The N-terminal domain facing the cytoplasm or nucleoplasm and containing a short basic region (RKRR).
In biochemistry, lipogenesis is the conversion of fatty acids and glycerol into fats, or a metabolic process through which acetyl-CoA is converted to triglyceride for storage in fat. [1] Lipogenesis encompasses both fatty acid and triglyceride synthesis , with the latter being the process by which fatty acids are esterified to glycerol before ...
