What does white adipose tissue look like?
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….

What is the difference between brown and white adipocytes?
White adipocytes, or white fat cells, have a single lipid droplet, but brown adipocytes contain many small lipid droplets, and a high number of iron-containing mitochondria. It is this high iron content that gives brown fat its dark red to tan color.
What is yellow adipose tissue?
Bone marrow fat, known as yellow adipose tissue (YAT), represents a depot dispersed throughout the bone marrow with primary localization to trabecular cavities [24, 25], and often viewed as having mixed characteristics of both WAT and BAT [25–27].
What is brown adipose?
Brown fat, also called brown adipose tissue, is a special type of body fat that is turned on (activated) when you get cold. Brown fat produces heat to help maintain your body temperature in cold conditions. Brown fat contains many more mitochondria than does white fat.
Where are brown adipocytes found?
Brown adipocytes are multilocular lipid storage cells that play a crucial role in non-shivering thermogenesis. These cells are located in brown adipose tissue (BAT) depots which are found in abundance in small mammals as well as in newborns of larger mammals, including humans.
Where are white adipocytes found?
White adipose tissue is the predominant type of fat in the human body. It can be found beneath the skin (subcutaneous fat), around internal organs (visceral fat), and in the central cavity of bones (bone marrow fat), as well as cushioning various parts of the body.
What are Brite adipocytes?
A brite adipocyte thus is a cell with the multilocular morphology and functional properties (including UCP1 expression) of brown adipocytes found in predominantly white adipose tissue depots with the definition being independent of the developmental origin.
What is the main differences between white and brown adipose CT?
The brown adipose tissue is almost completely depleted of fat. By contrast, the white adipose tissue contains ample fat, mostly in the form of single large vacuoles flattening the nuclei to one side.
What are adipocytes Class 11?
Adipose tissue, or fat, is an anatomical term for loose connective tissue composed of adipocytes. Its main role is to store energy in the form of fat, although it also cushions and insulates the body.
Where is brown adipose tissue found?
It is mainly located in the upper back, above the clavicles, around the vertebrae, and in the mediastinum. The main role of brown adipose tissue is to generate heat through non-shivering thermogenesis; a process that’s especially important to prevent hypothermia in newborns.
¿Cómo se genera el tejido adiposo blanco?
En el tejido adiposo blanco pue den generarse los animales como en humanos. Para ello se requiere teicos y lipídicos. Finalmente, el conocimiento actual modulación. Fig ura 2 con la técnica de hi stología y tinción.
¿Qué es la coloración parda del tejido adiposo?
La coloración parda del tejido adiposo se debe a que este se encuentra más vascularizado y con gran contenido de mitocondrias, las cuales, a su vez, poseen citocromos, responsables de dar color. Las células adiposas que conforman al tejido adiposo pardo son multiloculares o con varias vacuolas lipídicas.
¿Cuáles son las características de los adipocitos beige?
Aun cuando los adipocitos beige tienen características similares a los pardos, como su morfología (contienen varias vacuolas lipídicas), tienen distintas localizaciones anatómicas.
¿Cuáles son los diferentes tipos de células adipocíticas?
Respecto a las células que los componen, se sabe de al menos cuatro tipos de células adipocíticas (blanca, marrón, beige, rosa). Algunos autores incluyen también a las células estrelladas hepáticas o adipocitos azules. Recientemente, también han sido descritos los adipocitos amarillos. Tejido adiposo blanco.
