Abstract:
Reverse genetics has been used to generate recombinant Newcastle disease virus with enhanced immunogenic properties for vaccine development. The system, which involves co-transfecting the viral antigenomic plasmid with three helper plasmids into a T7 RNA polymerase-expressing cell to produce viral progenies, poses a great challenge. We have modified the standard transfection method to improve the transfection efficiency of the plasmids, resulting in a higher titer of virus progeny production. Two transfection reagents (i.e., lipofectamine and polyethylenimine) were used to compare the transfec

Intracellular gene delivery is normally required to study gene functions. A versatile platform able to perform both chemical transfection and viral transduction to achieve efficient gene modification in most cell types is needed. Here we demonstrated that high throughput chemical transfection, virus packaging, and transduction can be conducted efficiently on our previously developed superhydrophobic microwell array chip (SMAR-chip). A total of 169 chemical transfections were successfully performed on the chip in physically separated microwells through a few simple steps, contributing to the co

Abstract Biological research is relying on increasingly complex genetic systems and circuits to perform sophisticated operations in living cells. Performing these operations often requires simultaneous delivery of many genes, and optimizing the stoichiometry of these genes can yield drastic improvements in performance. However, sufficiently sampling the large design space of gene expression stoichiometries in mammalian cells using current methods is cumbersome, complex, or expensive.

Abstract:
Biodegradable and bioresponsive polymer-based nanoparticles (NPs) can be used for oligonucleotide delivery, making them a promising candidate for mRNA-based therapeutics. In this study, we evaluated and optimized the efficiency of a cationic, hyperbranched poly(amidoamine)s-based nanoparticle system to deliver tdTomato mRNA to primary human bone marrow stromal cells (hBMSC), human synovial derived stem cells (hSDSC), bovine chondrocytes (bCH), and rat tendon derived stem/progenitor cells (rTDSPC). Transfection efficiencies varied among the cell types tested (bCH 28.4% ± 22.87, rTDSPC 18.13% ±

Abstract:
A number of gene delivery methods have been developed to facilitate gene transfer into mammalian somatic cells in vivo. In this study, we demonstrated that tracheal insufflation of two recombinant plasmids containing a bacterial gene, chloramphenicol acetyltransferase (CAT), driven by the cytomegalovirus (CMV) immediate early promoter/enhancer, either alone or complexed to cationic liposomes, resulted in efficient and selective transfection of the lungs in rats. When the simian virus 40 (SV40) promoter/enhancer was used, there was no detectable transfection. Insufflation of plasmid DNA was as

Abstract:
Abstract The need for gamma-retroviral vectors with self-inactivating (SIN) long terminal repeats for clinical trials has prompted a shift in the method with which large scale GMP-grade vectors are produced, from the use of stable producer lines to transient transfection-based techniques. The main challenge of instituting this methodology was to develop SIN retrovirus vectors that produced high amounts of genomic vector RNA in packaging cells, and to design scalable processes for closed system culture, transfection and virus harvest. Using improved expression plasmids, the Vector Production Fa

Abstract:
ABSTRACTTransfection is a powerful tool for introducing foreign DNA into target cells. Many kits and methods are offered to simplify the process of introducing foreign DNA into cells. ZF4 is a cell type derived from zebrafish that is difficult to transfect. The majority of studies involving transfection into cells require transfection efficiency 70%. Our research demonstrates transfection using 2 kinds of methods, namely chemical transfection using X-tremeGene HP and electroporation-based transfection using a nucleofector device which will later be called Nucleofection. Our results show that t

Abstract:
Nitric oxide (NO) regulates vascular homeostasis and plays a key role in revascularization and angiogenesis. The endothelial nitric oxide synthase (eNOS) enzyme catalyzes NO production in endothelial cells. Overexpression of the eNOS gene has been implicated in pathologies with dysfunctional angiogenic processes, such as cancer. Therefore, modulating eNOS gene expression using small interfering RNAs (siRNAs) represents a viable strategy for antitumor therapy. siRNAs are highly specific to the target gene, thus reducing off-target effects. Given the widespread distribution of endothelium and th
