Functional and histologic evaluation in the C57 and b1/2-ARs KO chimera. (A) SCFA-producing bacteria and butyrate production in the feces. Percentages of acetate-, butyrate-, and lactate- producing bacteria in total gut microbiota. (B) No significant changes in the production of butyrate in the b1/2-ARs KO chimera. (C) Histology of C57 (a,b) and b1/2-ARs KO chimera (c,d) colons. (Frozen sections stained with hematoxylin and eosin, 100X (a,c) & 200X (b,d) magnification, all bars indicate 80 μm). No significant histopathologic lesions were detected in the colons of both C57 and b1/2-ARs KO chimera mice, and no qualitative differences were detected between the two groups.
