Efficient, Low-Cost Nucleofection of Passaged Chondrocytes.

Area of Science:

• Cell Biology
• Biotechnology
• Gene Therapy

Background:

• Nucleofection is an effective method for chondrocyte transfection.
• Commercial kits are expensive and limit accessibility for research and clinical use.

Purpose of the Study:

• To develop a cost-effective, nonviral nucleofection method for chondrocytes.
• To assess the efficiency and safety of laboratory-produced buffers for nucleofection.

Main Methods:

• Bovine-passaged chondrocytes were nucleofected using various in-laboratory buffers.
• Cell attachment, confluency, viability, and transfection efficiency were evaluated.
• Gene expression and protein levels were analyzed post-nucleofection.

Main Results:

• A novel buffer (1M) showed no significant difference in cell viability or attachment compared to controls.
• Nucleofection with 1M buffer achieved transfection efficiencies comparable to commercial kits.
• siRNA delivery resulted in significant knockdown of target proteins (Lamin A/C).

Conclusions:

• A cost-effective and efficient nucleofection method for bovine and human chondrocytes was identified.
• This method utilizes known buffer formulations, making it accessible for basic science and clinical translation.
• Facilitates cost-efficient gene targeting for articular cartilage repair research.
