Quantitative Fraction Evaluation of Dermal Collagen and Elastic Fibres in the Skin Samples Obtained in Two Orientations from the Trunk Region
Figure 2
Photograph showing the pattern of collagen (stained pink) and elastic (black stain) fibres as in Verhoeff-van Gienson (VVG) stain (×20) in horizontal (VVG/H) and vertical (VVG/V) samples of upper back (a), presternal (b), lateral chest (c), abdomen (d), and groin (e) areas of trunk region. Segmentation of collagen and elastic fibres by tissue-quant (TQ) image analysis is shown in adjacent photographs. TQ/CH and TQ/EH: for collagen and elastic fibres in horizontal section, respectively, and TQ/CV and TQ/EV: as in vertical sections, respectively.
