Abstract (original English)

Background Subcutaneous white adipose tissue (WAT) is crucial for systemic metabolic homeostasis, with beige adipocytes in this depot contributing to energy metabolism through inducible thermogenesis. Differentiated adipocyte cultures derived from mouse inguinal WAT are a widely used system to study beige adipose biology and identify therapeutic targets, as they retain the genetic and epigenetic traits of native adipocytes while providing experimental flexibility. However, variability during the adipocyte induction and differentiation poses a challenge, impacting beige adipogenesis and experimental outcomes. Methods This study conducted an unbiased analysis of four distinct adipogenic cocktails to evaluate their effects on beige adipogenesis in inguinal stromal vascular fraction cells from wild-type and genetically modified mice, as well as on the thermogenic activation of differentiated adipocytes. Results Different combinations of adipogenic inducers, including dexamethasone, 3-isobutyl-1-methylxanthine, insulin, triiodothyronine, indomethacin, and rosiglitazone (Rosi), recruited beige adipocytes with varying levels of thermogenic characteristics. The peroxisome proliferator-activated receptor gamma agonist, Rosi, emerged as a key inducer, maximizing beige adipocyte biogenesis during the differentiation phase rather than the induction phase. However, Rosi-enhanced beige adipo
