Cthrc1 localizes to the pituitary gland.

<p>Immunolocalization of Cthrc1 in human pituitary glands identifies cells expressing Cthrc1 in the anterior lobe (A, arrow). (B, C) Accumulations of colloid-like material contain Cthrc1 immunoreactivity. (D) Absence of non-specific staining is observed with an irrelevant monoclonal antibody. (E, F) Cells surrounding Cthrc1 immunoreactivity are of the chromophobe type. Cthrc1 immunoreactivity in brown with hematoxylin counterstain. Original magnification 200x (A-C), 100x (D), 400x (E, F).
