doi: 10.1016/j.mtbio.2024.101398
Figure Lengend Snippet: Effects of porcine pericardial decellularized matrix bilayer patches containing exosomes (dECM + collagen + Exo) on cells in vitro. (A) Morphological observations of three cell types after 1, 3, and 7 days of growth on the surface of bilayer matrix patches, (green: cytoskeleton, blue: DAPI). (B) Cells' viability after co-incubation of dECM + collagen + Exo and human skin fibroblasts, keratinocytes and HUVEC. (C) Transwell images of human skin fibroblasts when co-cultured with dECM + collagen + Exo bilayer patches. (D) dECM + collagen + Exo bilayer patches induced HUVEC formation tubes. (E) Statistical analysis with tube-forming branches (n = 5). (F) Western Blott evaluation of proliferation-related proteins (Ki67) and angiopoiesis-related proteins (VEGF) expressed by fibroblasts and HUVEC, respectively, n = 3, statistical significance was obtained by one-way ANOVA, ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
