TGF-β effects on adipogenesis of 3T3-L1 cells differ in 2D and 3D cell culture conditions.

ABSTRACT: The TGF-β superfamily plays a pivotal role in the regulation of adipogenesis, but little is known about the potential differential role of the three isoforms of TGF-β, TGF-β-1~3. To further elucidate their role, two-dimensionally (2D) and three-dimensionally (3D) cultured 3T3-L1 mouse preadipocytes were subjected to the following analyses: (a) qPCR analysis of adipogenesis-related factors and major extracellular matrix protein (2D and /or 3D), (b) lipid staining by Oil Red O (2D) or BODIPY (3D), (c) Seahorse cellular metabolic measurement (2D), and (d) size and stiffness measurements of 3D 3T3-L1 spheroids. In the 2D cultured 3T3-L1 cells, mRNA expression levels of adipogenesis-related genes and Oil Red O lipid staining intensity were significantly increased by adipogenesis and they were s
