FIG. 8.

Effects of PGG on host infiltration into acellular mitral valve scaffolds at 4 weeks postimplantation. (A) Representative histology images of leaflet (L) and chordae (C) scaffolds stained with Trichrome (collagen, blue; cells, red) and anti-CD8 antibody (positive, brown). (B) Quantitative analysis of total infiltrating cells (top) and CD8+ infiltrating cells (bottom), both normalized to scaffold cross-sectional area. Scale bars are 100 μm in Trichrome images and 20 μm in CD8 images. *p < 0.05 by ANOVA. ANOVA, analysis of variance. Color images available online at www.liebertpub.com/tea
