BMP4 expression was reduced in ER-deficient Min/+ mice. Representative immunohistochemistry of sectioned proximal colons from female WT and Min/+ mice compared with ERα+/−Min/+ and ERβ−/−Min/+ mice for BMP4 (A). Original magnification was ×40. Note, there is artificial uptake of antibody reagents with mucins in the goblet cells. Representative immunohistochemistry of sectioned proximal colons from study mice for Ihh (B). Original magnification was ×40.
