Where is adipose tissue found in the body? adipose tissue to prevent adipocyte dysfunction, and then the fibrosis, inflammation, IR related to obesity and metabolic diseases. Adipose tissue is composed of cells called adipocytes that collect and store fat in the form of triglycerides for energy metabolism. It is found mainly under the skin but also in deposits between the muscles, in the intestines and in When seeded with adipose-derived stem cells, dermal matrices induced cell differentiation toward an endothelial phenotype, exemplifying that intrinsic structural and instructive properties of the original tissue type remain in the acellular matrix. Adipose tissue is typically homogeneous and finely divided by faint septa. The fat cell is made up of connective tissue (cells, fibres, fluid) with adipocytes containing nuclei, receptors and lipid droplets of fat. Adipose tissue, when carried around in excessive amounts, predisposes to a large number of diseases. Its main role is to store energy in the form of fat, although it also cushions and insulates the body. Like every other tissue, adipose tissue consists of cells and extracellular matrix. Mast cells are also increased in obese adipose tissues, contributing to insulin resistance. Adipose tissue function depends on the type and location of fat within the body. Its main role is to store energy in the form of lipids, although it also cushions and insulatesthe body. Conclusion: This experimental study showed that adipose tissue engineering is feasible and gives comparable results to fat grafting.
