Adipocytes, also known as lipocytes and fat cells, are the cells that primarily compose adipose tissue, specialized in storing energy as fat. [1] Adipocytes are derived from mesenchymal stem cells which give rise to adipocytes through adipogenesis. In cell culture, adipocyte progenitors can also form osteoblasts, myocytes and other cell types.
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.
Histology features of a lipoblast, also known as an adipocyte precursor cell or preadipocyte.. Adipogenesis is the formation of adipocytes (fat cells) from stem cells. [1] It involves 2 phases, determination, and terminal differentiation.
In contrast to white adipocytes, which contain a single lipid droplet, brown adipocytes contain numerous smaller droplets and a much higher number of (iron-containing) mitochondria, which gives the tissue its color. [3] Brown fat also contains more capillaries than white fat. These supply the tissue with oxygen and nutrients and distribute the ...
White adipose tissue is composed of monolocular adipocytes. In humans, the healthy amount of white adipose tissue varies with age, but composes between 6–25% of body weight in adult men and 14–35% in adult women.
Kidney and nerve tissue cells can form memories much like brain cells, one new study has found. Another recent study says that memories of obesity stored in fat tissue may be partly responsible ...
Adipose tissue is an endocrine organ that secretes numerous protein hormones, including leptin, adiponectin, and resistin. [1] These hormones generally influence energy metabolism, which is of great interest to the understanding and treatment of type 2 diabetes and obesity.
