ABSTRACT
Tissue engineering scaffolds are intended to provide mechanical and biological support for cells to migrate, engraft and ultimately regenerate the tissue. Development of scaffolds with sustained delivery of growth factors and chemokines would enhance the therapeutic benefits, especially in wound healing. In this study, we incorporated our previously designed therapeutic particles, composed of fusion of elastin-like peptides (ELPs) as the drug delivery platform to keratinocyte growth factor (KGF), into a tissue scaffold, alloderm. The results demonstrated that sustained KGF-ELP release was achieved and the bioactivity of the released therapeutic particles was shown via cell proliferation assay, as well as a mouse pouch model in vivo, where higher cellular infiltration and vascularization were observed in scaffolds functionalized with KGF-ELPs.
