Proliferation and differentiation of adipose-derived stem cells (ADSCs) into mature adipocytes associate with development of obesity. Nutritional stimulation induces ADSCs proliferation and differentiation, but molecular mechanisms to maintain ADSCs in an undifferentiated and quiescent state are largely unknown. To identify genes essential for the mechanism, microarray analysis was performed using freshly isolated murine ADSCs and 4-day cultured ADSCs (preadipocytes). In ADSCs, 312 probes of transcriptional factors were up-regulated and we focused on nuclear receptor 4a subfamily (Nr4a1, Nr4a2, and Nr4a3), which play diverse roles including metabolic processes. We overexpressed each Nr4a receptor into ADSCs to evaluate the functions of differentiation. Nr4a over-expression decreased marker of adipogenic factors, which is altered by application of cAMP analogue. These data suggested that Nr4a1/2/3 inhibited cell proliferation and adipogenesis in a cAMP-dependent manner.
