Abstract
- Objective To study the antibacterial and tissue reparative effect of BPI-BD3 gene-modified mesenchymal stem cells in a mouse model of wound infection. Methods C3H10T1/2 cells were transfected with recombinant adenovirus vector pAdxsi-BPI-BD3, the expression of BPI-BD3 fusion protein was verified by RT-PCR and Western blotting. Excision wound with a diameter of 1cm was inoculated with Staphylococcus aureuswas made on the back of 30 mice. The mice were randomly divided into 3 groups (10 each). Mice in group T were injected with BPI-BD3 gene-modified C3H10T1/2 cells through caudal vein, those in group C were injected with unmodified C3H10T1/2 cells, and in group N were injected with PBS as control. The wound repair result was evaluated by estimation of the percentage of remaining wound area and the amount of wound bacteria under the scar, followed by observation of pathological changes. Inflammatory reactions of the wounds were assessed accordingly. Results The amount of bacteria under the scar was less in group T than in the other two groups (P
