area, and along the spinal cord. This is the smaller of the two types and has numerous small lipid droplets.
* Beige fat is the adrenergically inducible cell type that is dispersed throughout adipose tissue. It has greater variability in lipid droplet size and a greater proportion of mitochondria to lipid droplets than white fat, giving it a light brown appearance. In mouse and human organoid models, EPAC1 (exchange proteins directly activated by cAMP) was reported to preferentially increase the production of beige fat relative to WAT.
