Polyethylenimine (PEI), a cationic polymer, has been widely studied and shown great promise as an efficient gene delivery vehicle. Likewise, the HIV-1 Tat peptide, a cell-permeable peptide, has been successfully used for intracellular gene delivery. To improve the favorable properties of these two vectors, we combine PEI with the modified Tat peptide(More)
Regenerative procedures using barrier membrane technology are presently well established in periodontal/endodontic surgery. The objective of this study was to compare the subsequent effects of the released platelet-derived growth factor (PDGF) and growth/differentiation factor 5 (GDF-5) from collagen membranes (CMs) on bone regeneration in vitro and in(More)
A combination of modified HIV-1 Tat (mTat) peptide and cationic lipids, FuGENE HD (FH), dramatically enhanced transfection efficiency across a range of cell lines when compared to mTat or FH alone (Biomaterials 35:1705–1715 2014). The efficiency of this Tat peptide combination was significantly higher than many commercial non-viral vectors. In this present(More)
Bone regeneration is a complex, well-coordinated physiological process. Large quantities of bone regeneration are often required for craniofacial skeletal reconstruction of large bone defects created by trauma, tumor resection, infection, and skeletal abnormalities. Over the last two decades, a tissue engineering and regeneration approach has been developed(More)
