FIG. 2.

Histology (HES coloration) and immunostaining of reconstituted skin (n=4) prepared with methyglyoxal-modified collagen rich in hydroimidazolone: MG-H1 (B, D, F, H) as compared to control (A, C, E, G), and glycoxidized collagen (pentosidine [PEN] rich) (M, O, Q, S) as compared to control (L, N, P, R). Immunostaining against α6 integrin (C, D, N,O), laminin 5 (E, F, P, Q), and procollagen I (G, H, R, S). Surface staining was evaluated as in Figure 1 for α6 integrin surface (I, T), laminin 5 (J, U), and procollagen I (K, V). Means±SD are reported (*p<0.05). Laminin 5 is significantly decreased by methylglyoxal-modified collagen compared to control.
