Figure 3. Effects of LPS-induced acute inflammation on the mean fluorescence intensity (MFI) of mast cell tryptase (A) and c-kit (B) signals in cells double positive for mast cell tryptase and c-kit that are present in mesentery close to mesenteric lymphatic vessels in adult (9 mo, n=3 for control and n=3 for LPS-treated groups) and aged (24 mo, n=3 for control and n=3 for LPS-treated groups) rats. * indicates significant difference (p < 0.05, one-way ANOVA) between MFI of the mast cell tryptase signal in 9 mo control group vs other groups.
