Identification of infiltrating cells in implanted collagen scaffolds. PGG-stabilized scaffolds were compared to untreated control scaffolds. (a) Vimentin stain showing fibroblast-like cells at 4 weeks after implantation. (b) Prolyl-hydroxylase immunohistochemical staining: arrows point to positively stained cells. (c) Specific staining showing few infiltrated macrophages (arrows). Inset shows intense macrophage staining of rat spleen sections used as a positive control. (d) CD8 staining for infiltrating cytotoxic T lymphocytes. Inset shows intense CD8 staining of rat spleen sections used as a positive control. Sections were counterstained with hematoxylin (nuclei dark blue). Bars are 50 μm in all micrographs.
