New Concept and Apparatus for Cytocentrifugation and Cell Processing for Microscopy Analysis

Area of Science:

• Cell Biology
• Microscopy Techniques
• Biotechnology

Background:

• Cytocentrifugation is a standard method for preparing cell samples on slides.
• Conventional cytocentrifugation requires specialized equipment like cytocentrifuges or cytorotors and cassettes.
• Existing methods can be costly and may involve complex procedures.

Purpose of the Study:

• To introduce and evaluate a novel cytocentrifugation concept using a threaded lid and sample holder design.
• To develop an inexpensive device for cell sample preparation on coverslips.
• To assess the device's efficacy for various cell types and subcellular components.

Main Methods:

• Development of a new cytocentrifugation device with an adjustable flow system.
• Testing the device for capturing eukaryotic and prokaryotic cells, nuclei, and mitochondria.
• Optimization of a procedure for capturing formaldehyde-fixed cells without drying.

Main Results:

• The developed device effectively captures and processes diverse cell samples, including eukaryotic cells, prokaryotic cells, nuclei, and mitochondria.
• An efficient method for preserving formaldehyde-fixed cells on coverslips was established.
• The device demonstrated comparable performance to traditional cytocentrifuges but at a lower cost.

Conclusions:

• The novel cytocentrifugation concept and device provide an effective and economical alternative to conventional methods.
• The system simplifies sample preparation, reduces consumable costs (only paper filters are used), and eliminates the need for specialized centrifuges.
• The design facilitates potential automation of staining procedures due to integrated solution management.
