Vascular density in TLR2KO and TLR4KO mice.

<p>Representative photomicrographs of CD31 (A) and SMA (B) staining in tibialis anterior muscle from the ischemic hind limb of control, TLR2 KO and TLR4 KO mice two weeks after femoral artery ligation (Scale bar = 25 µm). (C) Quantification of vessels measuring greater than 30 µm² is shown (N = 4 per group; *P<0.05, TLR2 KO vs. TLR4 KO or control).
