ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of PDGF on dermal blood vessel reconstruction by transplanted tissue-engineering skin containing PDGF-B gene to rats.</p><p><b>METHODS</b>The recombined eukaryotic expression vector, pcDNA3.1-hPDGF-B, was constructed and transfected into fibroblasts mediated by LipofectAMINE. Keratinocytes + acellular dermal matrix (group A), keratinocytes + acellular dermal matrix + fibroblasts (group B), keratinocytes + acellular dermal matrix + fibroblasts with PDGF gene (group C) were recombined respectively, then transplanted them to rat dorsum and evaluated the reconstruction of blood vessels in the dermis after 2, 4, 6 week postoperation.</p><p><b>RESULTS</b>In 2-4 weeks after skin grafting the vascularization rate in group C was higher than that of group B and group A. The vascularization rates in all groups had no significant differences in six weeks (P > 0.05).</p><p><b>CONCLUSION</b>PDGF-B gene plays an important role in reconstruction of blood vessels in the dermis at early tissue-engineering skin grafting, which ensures the take of grafted tissue-engineering skin.</p>
