Photomicrographs illustrating the optical density of the connective tissue as well as examples of ED1/DAPI- and H&E stained sections. Optical density of the explanted connective tissue was classified as (a) translucent, (b) translucent-opaque, and (c) opaque. (d) Example photomicrograph showing DAPI-stained nuclei in blue and ED1-immunopositive cells in red; scale bar 100 μm. (e) Example photomicrograph of a H&E stained section through the analyzed connective tissue; scale bar 250μm.
