Application of this protocol can be found in a DECODED newsletter article [2]. However, progress in in utero systems of electroporation into mouse embryos has opened a new window, permitting new approaches to answering important questions. In 1754 electroporation was first demonstrated on human and animal skin by applying electrical sparks though the phenomenon was not identified as electroporation . 3) the process of multiplication of the cells. Electroporation is a non-invasive alternative to the traditional mesotherapy therefore it is so-called virtual or needle-free mesotherapy (painless procedure). Namely, viral vectors can have serious limitations in terms of immunogenicity and pathogenicity when used for DNA transfer. Importantly, electroporation is effective in virtually every animal model tested to date and has a favorable safety profile, which is promising for clinical application. Third, gene delivery by highly precise and controlled electroporation will enable observation of cellular dynamics after genetic manipulation.

In the recent years a novel method of gene transduction appeared in the field of in vivo electroporation. A phenomenon that transiently increases the permeability of the cells is known as electroporation. Electroporation is a biotechnological technique which subjects cells to strong (~kV/cm), short (~ms) electric field pulses that open pores on the cells’ plasma membranes. Electroporation is a delivery method that is used to introduce macromolecules such as proteins into cells, either in vivo or in vitro, via the application of brief electric pulses which induce momentary and reversible permeabilization of the cell membrane. Thus the electroporation system is an important mechanism for cell therapy, genetic therapy and drug Basic concepts that are required to understand electroporation and generation of pulsed electric fields from an electrical point of view, main effects of the treatments on microbial, plant and animal cells, techniques and research procedures to investigate electroporation and the most recent applications of PEF in the food industry will be presented by experts in the field.
