Beneficial effects of FMT on the small intestine and the level of serum endotoxin. (A) HE staining of the small intestine showing that FMT restored HFD-induced mucosal damage. (B) Immunohistochemistry for ZO-1 showing that FMT increased ZO-1 expression. (C) ZO-1 mRNA expression in the small intestine. (D) The level of serum endotoxin. The data represent the mean ± S.E.M. (n = 12 mice per group), * P < 0.05, ** P < 0.01 and *** P < 0.001.
