3T3-L1 is a
cell line derived from (mouse)
3T3 cells
3T3 cells are several cell lines of mouse embryonic fibroblasts. The original 3T3 cell line (3T3-Swiss albino) was established in 1962 by two scientists then at the Department of Pathology in the New York University School of Medicine, George Tod ...
that is used in biological research on
adipose tissue
Adipose tissue, body fat, or simply fat is a loose connective tissue composed mostly of adipocytes. In addition to adipocytes, adipose tissue contains the stromal vascular fraction (SVF) of cells including preadipocytes, fibroblasts, vascular ...
. 3T3-L1 cells have a
fibroblast-like
morphology
Morphology, from the Greek and meaning "study of shape", may refer to:
Disciplines
* Morphology (archaeology), study of the shapes or forms of artifacts
* Morphology (astronomy), study of the shape of astronomical objects such as nebulae, galaxies ...
, but, under appropriate conditions, the cells
differentiate into an
adipocyte-like
phenotype
In genetics, the phenotype () is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological pr ...

3T3-L1 cells of the adipocyte morphology increase the synthesis and accumulation of
triglyceride
A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from ''wikt:tri-#Prefix, tri-'' and ''glyceride'').
Triglycerides are the main constituents of body fat in humans and other ...
s and acquire the signet ring appearance of adipose cells. These cells are also sensitive to lipogenic and lipolytic hormones, as well as drugs, including
epinephrine,
isoproterenol
Isoprenaline, or isoproterenol (brand name: Isoprenaline Macure), is a medication used for the treatment of bradycardia (slow heart rate), heart block, and rarely for asthma. It is a non-selective β adrenoceptor agonist that is the isopropyla ...
