abstract：:Reports vary on the role of growth hormone (GH) in adipocyte differentiation. In this study, we showed that GH exerted dual effects depending on the stage of differentiation, using a serum-free culture of 3T3-L1 preadipocytes. GH promoted the differentiation when added to the medium during differentiation-inducing tre...
