Fig 1 Morphologic analysis of day 28 mouse vein grafts. A-B, Representative Masson's trichrome stained images. A, Normal saline suspended in pluronic F-127 gel (gNS) vein graft. B, Lipopolysaccharide suspended in pluronic F-127 gel (gLPS) vein graft. Scale bar = 200 μm. C, The comparison of vein graft lumen area, intimal thickness, media+adventitia thickness, the perimeter of internal elastic lamina, and the perimeter of outside boundary, based on Masson's stained images. Values are shown as mean ± standard error of the mean.

A, Vein graft (VG) wall at baseline day 0, and postoperative days 1 and 3. §Relative to normal saline suspended in pluronic F-127 gel (gNS) VG at the same time point, P < .05. B, VG wall at postoperative day 3. *Relative to normal inferior vena cava (IVC), P <.05; §Relative to gNS VG (with gNS adipose), P < .05; †Relative to gNS VG (with lipopolysaccharide suspended in pluronic F-127 gel [gLPS] adipose), P < .05. C, Distant (flank) adipose tissue at postoperative day 3. *Relative to normal adipose, P < .05; §Relative to gNS adipose (with gNS VG), P < .05; †Relative to gNS adipose (with gLPS VG), P < .05.

Supplementary Fig (online only) CD45 immunohistochemical analysis of day 28 mouse vein grafts. A, Representative image of normal saline suspended in pluronic F-127 gel (gNS)-treated vein graft. B, Representative image of lipopolysaccharide suspended in pluronic F-127 gel (gLPS)-treated vein graft. The hand-digitally drawn yellow lines delineate the internal elastic laminas of vein graft walls. Red arrows show the representative positive cells. Scale bar = 50 μm. C, Quantitative analysis based on CD45 immunohistochemical images. Values are shown as mean ± standard error of the mean. There is no statistical difference between two groups for the various vascular wall layers.
