Laser-based gene transfection and gene therapy.

Area of Science:

• Cell Biology
• Biotechnology
• Optical Engineering

Background:

• Mammalian cell membranes can be temporarily permeabilized using optical methods.
• This allows for the introduction of exogenous materials or genes into the cytoplasm of living cells.
• Existing manipulation techniques include laser optoinjection, stress waves, photochemical internalization, and light-absorbing particle irradiation.

Purpose of the Study:

• To review advancements in laser-assisted cell transfection.
• To analyze the advantages and disadvantages of four distinct laser-assisted transfection techniques.
• To highlight the universality of laser-assisted optoporation across different cell lines.

Main Methods:

• Review of literature on laser-assisted cell transfection methods.
• Analysis of techniques including direct laser optoinjection, laser-induced stress waves, photochemical internalization, and targeted irradiation with light-absorbing particles.
• Evaluation of universality and efficiency across various mammalian cell lines.

Main Results:

• Significant progress has been made in laser-assisted cell transfection techniques.
• Each method (optoinjection, stress waves, photochemical internalization, particle irradiation) presents unique advantages and disadvantages.
• Laser-assisted optoporation demonstrates broad applicability to diverse cell lines.

Conclusions:

• Laser-assisted optoporation is a promising technique for efficient gene and material delivery into cells.
• Its key advantage lies in its universality, making it adaptable to a wide range of cell types.
• This technique offers a significant improvement over existing cell transfection methods.
