Figure 2. Analysis of cAMP concentration. After 27 EMfCs treatment, the concentration of cAMP was measured in the supernatant of primary adipocytes treated with 27 EMfCs (200 µg/mL) that were fermented for 3 weeks (A), 4 weeks (B) and 6 weeks (C). The cell images of the three groups were observed with an inverted microscope at 100× magnification. The data shown represent the means±SD of three replicates. ^*P<0.05 relative to the Vehicle treated group. ISOP; isoproterenol.
