Figure 5 Verhoeff's stain for elastic tissue staining of the slices in Figure 2A. Elastic fibers stain black, whereas collagen stains red. The white dashed line (white arrow) shows the border between the collagen implant (left side) and the native collagen deposition (right side). The collagen implant is homogeneous without elastic fibers within the implant. The native collagen deposition demonstrates bundle formation with elastic fibers (yellow arrows) (x400).
