FIG. 4.
Transmission electron microscopy results showing mitochondria and amounts of mtDNA in WAT of female SSAT and Wt mice. (A) Electron microscopy of mitochondria in WAT of 7-month-old female SSAT and Wt mice. Mitochondria from eight SSAT and Wt mice were photographed at ×25,000 magnification. (B) mtDNA amounts in female 6-month-old SSAT and Wt mice, analyzed by quantitative RT-PCR. Results are presented as means ± SEM from six to seven mice per group. *, P < 0.05.
