Dietary supplementation with probiotics affects skin histology of mice.

<p>(<b>A</b>) Probiotic-fed C57BL/6 male mice differ from their control diet-fed counterparts by having subcutaneous hair follicle profiles and a thicker skin. Hematoxylin and Eosin. Bars = 250 µm. Histomorphometrical analysis reveals significant (P<0.0001) probiotic diet-associated increase in (<b>B</b>) skin thickness and (<b>C</b>) subcutaneous hair follicles in both genders. The y-axis depicts the mean±SEM of histomorphometric counts in each experimental group.</p>
