REA^d/d mice have decreased neonatal uterine cell proliferation and increased apoptosis. A, Representative histologic sections of BrdU immunohistochemistry in uteri of REA^f/f and REA^d/d d-14 mice. Note decreased BrdU incorporation in the REA^d/d uterus. Scale bar, 200 μm. B, Representative fluorescence images of TUNEL staining in uterine sections from REA^f/f and REA^d/d d-14 mice. C, Immunohistochemical detection of active-caspase-3 in uteri of REA^f/f and REA^d/d d-14 mice. Scale bar, 100 μm.
