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
Adipogenesis is the formation of adipocytes (fat cells) from stem cells. [1] It involves 2 phases, determination, and terminal differentiation. Determination is mesenchymal stem cells committing to the adipocyte precursor cells, also known as lipoblasts or preadipocytes which lose the potential to differentiate to other types of cells such as ...
Example of breast augmentation by fat grafting. Stem cell fat grafting is the autotransplantation of adipose-derived stem cells (ADSCs) extracted from fat-abundant donor sites (e.g. thigh or stomach) to other areas such as the face, breast, and hip to reconstruct the operative areas into desirable shapes. [1]
One known example of this kind of memory is what happens to pancreatic cells when they are exposed to a large amount of sugar. In response, they release into the bloodstream a pulse of insulin, a ...
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 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 ...
It is stored in different depots to gynoid fat: android fat is stored in the lower body and can present a so-called "triangle-shaped" body, while gynoid fat is stored in the upper body and can result in a "apple-shaped" body. Android fat cells are mostly visceral - they are large, deposited deep under the skin and are highly metabolically active.
Recent studies have shown the importance in non-coding RNA's ability to regulate cell differentiation and organismal development. There are many types of non-coding RNA that are present and play a role in differentiating stem cells. There are many non-coding RNAs responsible for differentiating cells for human brain and muscle development.
