Abstract
The goal of this proposal is to use stem cells with skin substitute transplantation to improve chronic wound healing in diabetes. The hypothesis to be tested is that the performance of marrow-derived progenitor cells in accelerating diabetic wound healing may be enhanced by genetic modification to overproduce a vasculogenic cytokine. The following are the two specific aims of the proposed study: 1. To develop adeno-associated viral (AA V -2) vectors with exogenous vascular endothelial growth factor (VEGF) gene for use in transducing bone marrow progenitor cells. These genetically modified bone marrow derived progenitors will then be seeded into an FDA approved artificial skin substitute. 2. To evaluate effects of skin substitutes loaded with AA V2-VEGF gene modified marrow progenitor cells on promotion of wound healing in chronic wounds in db+/db+ diabetic mice. This work is the extension of our ongoing efforts to promote soft tissue healing with gene transfer of growth factors by extending the target cells to bone marrow progenitors.
