Sirius red staining of fibrillar collagens. Sirius red staining of dermal fibroblasts: untreated (A), TGF-β1 treated (B) and PDGF-AB treated (C). The deceullularized matrix from dermal fibroblasts: untreated (D), TGF-β1 treated (E) and PDGF-AB treated (F). Sirius red staining of pulmonary fibroblasts: untreated (G), TGF-β1 treated (H) and PDGF-AB treated (I). The deceullularized matrix from pulmonary fibroblasts: untreated (J), TGF-β1 treated (K) and PDGF-AB treated (L). The experiments were done on dermal donor one and pulmonary donor two.
