From: Mesenchymal stem cells modified with angiopoietin-1 gene promote wound healing
Masson’s trichrome staining for collagen. (A) Representative trichrome-stained images at day 21 after treatment. Angiopoietin-1 gene-modified bone marrow mesenchymal stem cell (Ang1-MSC)-treated wounds showed an arranged collagen network, indicating more mature collagen development than in the other groups. Scale bar = 50 μm. (B) Ang1-MSC-treated wounds display much denser collagen than wounds in the other groups. Analysis of variance versus mesenchymal stem cells (MSCs), recombinant adenovirus encoding angiopoietin-1 (Ad-Ang1) or sham, *P <0.05.
