The establishment of the IR model of 3T3-L1 adipocytes. a The inducing of 3T3-L1 preadipocytes for 8 days and the identification of mature adipocytes by oil red O staining (×200). b The free fatty acid of 3T3-L1 preadipocytes and adipocytes. (n = 10). Comparison in two groups, ^##p < 0.01. c The effects of different concentrations of dexamethasone on glucose consumption (up panel) and consumption decrement (down panel) in 3T3-L1 adipocytes (n = 10). ^##p < 0.01, compared with control group. d The effects of 1 μmol/L dexamethasone on glucose consumption and glucose consumption decrement for different time in 3T3-L1 adipocytes (n = 10). Comparison in two groups, ^##p < 0.01
