Immunohistochemical analysis of CCR8 and TCA3 up-regulation in injured femoral arteries. Serial sections from femoral arteries from mice 5 days after injury (B,D-F) and from uninjured mice (A,C) were stained for macrophages, MOMA-2 (E, 1:400 dilution), smooth muscle α-actin (F, 1:100 dilution), CCR8 (C-D, 1:5000 dilution), or TCA3 (A-B, 1:10 dilution). Magnification shown is × 40. Cells that stain for CCR8 and TCA3 stain for smooth muscle cell α-actin and both CCR8 and TCA3 are induced in injured vessel. Only rare cells stain for Moma-2.
