New Approaches to Old Techniques in Cell Handling for Microscopy

Area of Science:

• Cell Biology
• Microscopy Techniques
• Molecular Biology

Background:

• High-quality cell preparation is crucial for reliable experimental data.
• Traditional methods for cell preparation, such as cytospins and specialized chamber slides, can be costly and labor-intensive.
• Adherent and suspension cells require distinct preparation techniques for microscopy.

Purpose of the Study:

• To develop simplified, cost-effective homemade methods for preparing both suspension and adherent cells for microscopy.
• To enable large-volume cell functional assays followed by microscopic evaluation without specialized equipment.
• To present practical protocols and examples for cell preparation in research settings.

Main Methods:

• Development of simplified, do-it-yourself (DIY) protocols for preparing suspension cells (e.g., murine splenocytes) and adherent cells (e.g., human tumor cell lines).
• Elimination of the need for cytospins, specialized chamber slides, or round coverslips.
• Focus on achieving optimal cell concentration, preservation, and minimizing artifacts for microscopy.

Main Results:

• Successful implementation of homemade cell preparation techniques for both cell types.
• Demonstrated feasibility of performing large-volume cell functional tests, including cellular uptake of self-delivering oligonucleotides.
• Obtained high-quality microscopy data with minimal artifacts and satisfactory cell preservation.

Conclusions:

• Simplified homemade cell preparation methods offer a viable and accessible alternative to traditional techniques.
• These methods facilitate robust cell-based assays and microscopy, particularly for researchers with limited resources.
• The presented approaches enhance the efficiency and quality of cell analysis in diverse biological studies.
