Fig. 2. Effect of PLA, ILA, and LA on hMSC differentiation.
(A) Microscopic pictures. Images were captured using an inverse phase contrast microscope at a magnification of 25×. Scale bars represent 200 μm. (B) Triglyceride (TG), glycerol, and free fatty acid (FFA) levels. NOR, normal groups, preadipocytes; CON, control groups, cells were cultured with differentiation medium; compound-treated groups (PLA, ILA, and LA), cells were cultured with differentiation medium and treated with 0.31 to 10 mM concentration with each compound. Data represent the means ± standard deviation (SD). *p < 0.05 indicates statistical differences between CON and experimental groups.
