Effect of White Tea extract solution on ADD1/SREBP-1c expression during adipogenesis. Preadipocyte populations (0 d) were incubated with differentiation medium without (A) and with (B) 0.5% White Tea extract solution for 10 days. A and B: ADD1/SREBP-1c was detected by immunofluorescence microscopic analysis. Scale bar: 200 μm. C-E: Quantitative analyses were performed using the Odyssey Infrared Imager. 1 and 3: Cells incubated in control solution. 2 and 4: Cells incubated in the presence of White Tea extract solution. For experiments, 17 independent cell cultures were prepared both for control and White Tea extract solution incubation (n = 17). Results are depicted as mean ± SD. Significant differences are marked with an asterisk (* for p < 0.0001).
