Cold exposure physiologically induces the browning process by sympathetic fiber innervation via a β3-adrenergic stimulation of white adipose tissue (WAT). The beige phenotype, enriched with mitochondria, allows for non-shivering thermogenesis like brown adipocytes due to the expression of UCP1. Photographs represent hematoxylin and eosin (HE) staining of WAT, WAT-derived brown-like adipose tissue (wBAT) and brown adipose tissue (BAT) in mice.
