M1/M2 Macrophages Play Different Roles in Adipogenic Differentiation of PDGFRα+ Preadipocytes In Vitro

Background PGGFRα+ preadipocytes are the major subpopulations that can regenerate into adipocytes. Two different types of macrophages exist in the fat tissue: the classically activated macrophage (M1) and the alternatively activated macrophage (M2). In this study, we investigated whether M1/M2 macrophages play distinct roles in adipogenic differentiation of PDGFRα+ preadipocytes.
