Visceral fat findings in the control, MSG, and MSG + FOS mice at 18 weeks. a Histological findings (hematoxylin/eosin staining, 100× magnification, scale bar = 100 μm), b Flow cytometric analysis of ATM. ATM were defined as F4/80⁺ CD11b^high cells. Among the ATM, M1-like macrophages were defined as CD11c⁺ cells. c MFI ratio of CD86 in F4/80⁺ CD11b^high CD11c⁺ cells. ATM, adipose tissue macrophages; FOS, fructo-oligosaccharides; MSG, monosodium glutamate; MFI, mean fluorescence intensity
