Spermatogonial stem cells (SSCs) are the only stem cells in adults that can transfer genetic information to the future generations. Considering the fact that a single SSC gives rise to a vast number of spermatozoa, genetic manipulation of these cells is a potential novel technology with feasible application to various animal species. The aim of this study was to evaluate enhanced green fluoresc...
This study reports the potential of cold atmospheric plasma (CAP) as a versatile tool for delivering oligonucleotides into mammalian cells. Compared to lipofection and electroporation methods, plasma transfection showed a better uptake efficiency and less cell death in the transfection of oligonucleotides. We demonstrated that the level of extracellular aqueous reactive oxygen species (ROS) pro...
We investigated the function of Xrx1 during Xenopus retinogenesis. Xrx1 overexpression lengthens mitotic activity and ectopically activates the expression of markers of undifferentiated progenitors in the developing retina. We assayed Xrx1 ability to support proliferation with a cell-autonomous mechanism by in vivo lipofection of single retinal progenitors. Xrx1 overexpression increases clonal ...
Using the lipofection reagent LipofectAMINE 2000 we have examined the delivery of plasmid DNA (5-200 kb) to mouse embryonic stem (mES) cells by flow cytometry. To follow the physical uptake of lipoplexes we labeled DNA molecules with the fluorescent dye TOTO-1. In parallel, expression of an EGFP reporter cassette in constructs of different sizes was used as a measure of nuclear delivery. The ce...
Liposomal magnetofection is a simple, highly efficient technology for cell transfection, demonstrating better outcome than a number of other common gene delivery methods. However, aggregate complexes distribution over the cell surface is non-uniform due to the gradient of the permanent magnetic field. The aim of this study was to estimate the efficiency of liposomal magnetofection for prostate ...
The Vax2 homeobox gene plays a crucial role in early dorsoventral patterning of the eye. However, although Vax2 transcripts have been detected in later differentiating eye and brain regions, its possible roles at these stages are still unclear. By immunohistochemistry and in situ hybridization, we extensively compared the expression patterns of Xenopus Vax2 (Xvax2) mRNA and protein. Expression ...
Survivin gene may be a good target for cancer gene therapy because it is over expressed in a variety of human tumors including human hepatocellular carcinoma but not in differentiated adult tissues. To explore the effects of the siRNA of survivin gene inducing apoptosis in human hepatocellular cancer cells, three siRNAs cpusiRNA1, cpusiRNA2 and cpusiRNA3 were designed and transferred into human...
Microbubbles and ultrasound have recently been investigated with a view to improving the transfection efficiency of non-viral gene delivery systems. However, microbubbles are unstable and their targeting ability is insufficient for clinical use. To circumvent these problems, we developed novel polyethyleneglycol (PEG) modified liposomes (Bubble liposomes) containing perfluoropropane, which is a...
