Effects of germ-free conditions on oligodendrocytes and mature oligodendrocytes. (A) Representative images showing all oligodendrocytes (Olig2+) and mature oligodendrocytes (Olig2+CC1+) within the PFCWM of control (C) and germ-free (GF) piglets at P16. Scale bar, 50 μm. White arrows demarcate double positive cells. Quantification of the number of Olig2+ (B) and Olig2+CC1+ (C) cells in PFCWM, CC-Genu, CC-Body, and CC-Splenium in P0-C, P16-C, and P16-GF animals. Individual male and female animals are marked by orange triangles and circles, respectively. Data expressed as mean ± SEM, n = 3–6 animals/group. ****p < 0.0001, two-way ANOVA; *p < 0.05, **p < 0.01, unpaired student’s t-test.
