The use of synthetic mRNA as an alternative gene delivery vector to traditional DNA-based constructs provides an effective method for inducing transient gene expression in cell cultures without genetic modification. Delivery of mRNA has been proposed as a safer alternative to viral vectors in the induction of pluripotent cells for regenerative therapies. Although mRNA transfection of fibroblast...
BACKGROUND MicroRNAs are small noncoding RNAs about 22 nt long that play key roles in almost all biological processes and diseases. The fluorescent labeling and lipofection are two common methods for changing the levels and locating the position of cellular miRNAs. Despite many studies about the mechanism of DNA/RNA lipofection, little is known about the characteristics, mechanisms and specific...
BACKGROUND Adenovirus-assisted lipofection has been reported to increase transfection efficiency through mechanisms potentially involving endosome escape and/or nuclear targeting activity. Similarly, transfection with the viral fusogenic peptide HA-2 of the influenza virus hemagglutinin can increase transfection efficiency. However, there are few studies examining the mechanism and intracellula...
Although many in vitro gene transfer methods already exist, such as calcium phosphate precipitation, electroporation, or cationic liposomes, these methods cause significant cell injury and cell death. The study of the biology of endogenous autocrine-paracrine vasoactive systems such as the renin-angiotensin system in vascular cells is limited by the lack of a suitable gene transfer method with ...
Gene transfer into CNS is critical for potential therapeutic applications as well as for the study of the genetic basis of neural development and nerve function. Unfortunately, lipid-based gene transfer to CNS cells is extremely inefficient since the nucleus of these post-mitotic cells presents a significant barrier to transfection. We report the development of a simple and highly efficient lip...
BACKGROUND Transfection efficacy after nonviral gene transfer in primary epithelial cells is limited. The aim of this study was to compare transfection efficacy of the recently available method of nucleofection with the established transfection reagent FuGENE6. METHODS Primary human keratinocytes (HKC), primary human fibroblasts (HFB), and a human keratinocyte cell line (HaCaT) were transfect...
sperm mediated gene transfer can be an inexpensive and simple method in animal transgenesis; however its efficiency is poor, mainly due to the spermatozoa’s lesser uptake of exogenous dna. in the present study, the effects of lipofection and other augmentation techniques, such as sperm freezing and spermatozoa treatment with triton x100 and dmso, on exogenous dna uptake by sheep spermatozoa and...
background: p19 cells are mouse embryonic carcinoma cells which contain pluripotent ability, like stem cells, to differentiate into different cell lines. there are several properties for this cell line that make it a valuable cell model for study of developmental stages. methods: at the first step, pts2-egfp coding sequence which was cloned in pucd2.hygro vector was used for transfection in to ...
