Objectives: We investigated whether membrane free stem cell extract from adipose tissue (MFSCE) has anti-diabetic effect. Methods: To determine glucose uptake effect of MFSCE, we carried out glucose uptake assay in 3T3-L1 adipocytes. The regulatory mechanisms of MFSCE on glucose uptake were examined by Western blot analysis. Results: When MFSCE was treated to adipocytes at the concentration of 0.5, 1, 2.5, and 5 μg/mL, 2-deoxyglucose-6-phosphate uptake was elevated approximately 1.8-fold compared to cells not treated with MFSCE. It indicated that MFSCE enhances glucose uptake in 3T3-L1 adipocytes. In addition, MFSCE reduced phosphorylation of insulin receptor substrate-1 at serine 307 and induced Akt and glucose transporter 4 protein expressions that were related to insulin signaling. Furthermore, MFSCE regulated adenosine monophosphate-activated protein kinase (AMPK) pathway by increases of increase phosphorylation of AMPK and acetyl-CoA carboxylase that were related to AMPK pathway. Conclusions: These results indicated that MFSCE promotes glucose uptake via modulation of insulin signaling and AMPK pathway. Therefore, MFSCE could be a promising agent for treatment of diabetes mellitus.
