Effects of ginseng extract (GE), ginsenosides (GSs), and testosterone (T) on lipid accumulation in 3T3-L1 cells. (A) The 3T3-L1 preadipocytes were differentiated into mature adipocytes and then treated with GE, GSs, and/or T. At day 8 post-induction, the cells were fixed, and neutral lipids were stained with Oil Red O (representative cells are shown). (B) Quantitative analysis of triglyceride content. All values are expressed as mean ± SD. *
