In order to test associations between eating probiotic yogurt and
appearance of hair coat, we first used microscopy–assisted
histomorphometry from C57BL/6 mice (Fig. 2A). We found an
increase in thickness of dermis (Fig. 2B) in mice supplemented with
yogurt when compared with mice consuming control chow alone.
Quantitative assessment of skin thickness involved measuring the
distance from the epidermis to paniculus carnosus. In C57BL/6
mice, females eating probiotic yogurt had a greater dermal
thickness (457.1664.86 pixels) than control females (314.7660.06)
eating regular chow alone (Fig. 2B). Males displayed a similar
trend when eating yogurt (357.9663.87) compared with control
male animals (249.8648.75). Consumption of probiotic-rich diet
correlated with a significant increase of skin thickness (P,0.0001)
in both genders
