From: Mesenchymal stem cells modified with angiopoietin-1 gene promote wound healing
Angiopoietin-1 gene-modified bone marrow mesenchymal stem cells promote angiogenesis. (A) Representative images showing CD31 staining (yellow) on day 7 after wound treatment with angiopoietin-1 gene-modified bone marrow mesenchymal stem cells (Ang1-MSCs), recombinant adenovirus encoding angiopoietin-1 (Ad-Ang1), mesenchymal stem cells (MSCs), and sham. Scale bar = 50 μm. (B) Capillary density was increased in Ang1-MSC-treated wounds compared with MSC-treated, Ad-Ang1-treated, and sham-treated wounds. Analysis of variance versus MSCs, Ad-Ang1 or sham, *P <0.05.
