Shock wave permeabilization offers a novel physical gene transfer method for mammalian cells. This technique facilitates naked DNA uptake, showing promise for targeted in vivo gene therapy applications.

Area of Science:

  • Biotechnology
  • Cell Biology
  • Gene Therapy

Background:

  • Physical methods for naked DNA uptake into mammalian cells exist.
  • Current methods often have limitations for in vivo therapeutic applications, particularly in solid organs.

Purpose of the Study:

  • To introduce shock wave permeabilization as a novel physical gene transfer method.
  • To evaluate its potential for in vivo therapeutic applications.

Main Methods:

  • Utilized lithotripter-generated shock waves to induce temporary membrane permeability in eukaryotic cells.
  • Demonstrated shock wave transfection of various cell lines with naked plasmid DNA.

Main Results:

  • Shock waves cause temporary cell membrane permeabilization via cavitation and transient pore generation.
