(A) Immunostaining shows nuclear translocation of NF-kB (red) in Tlr4f/f and Tie2Cre/+Tlr4f/f mice after exposure to LPS (40 μg/mouse) for 1 hour. Arrow heads indicate endothelial cells. Scale bar, 20 μm.
(B and C) LPS-induced expression of Cd14 by radioactive in situ hybridization (B) in day 16 decidual endothelial cells in Tlr4f/f and Tie2Cre/+Tlr4f/f mice. The lower panel (C) represents H&E-stained images. Arrow heads indicate endothelial cells. Scale bar, 200 μm.
