Mechanical Dissociation of Tissues for Single Cell Analysis Using a Motorized Device

Area of Science:

• Biomedical research
• Cell biology
• Laboratory automation

Background:

• Single-cell isolation is critical for biomedical research but manual methods are time-consuming and variable.
• Automated methods reduce time and variability but are often expensive and inaccessible.
• Lower-resourced laboratories need cost-effective solutions for single-cell preparation.

Purpose of the Study:

• To develop a low-cost, semi-automated device for tissue dissociation.
• To provide a reproducible and accessible alternative to manual and expensive automated methods.
• To facilitate single-cell analysis in academic research settings.

Main Methods:

• Fabrication and assembly of a semi-automated device using commercially available materials.
• Development of a semi-automated tissue dissociation protocol.
• Validation of the protocol across multiple mouse tissues.
• Creation of accompanying software for protocol customization.

Main Results:

• The device reliably produces single-cell suspensions with comparable cell yields and viability to manual methods.
• The protocol processes up to 12 tissue samples simultaneously, improving efficiency for large studies.
• The system offers a cost-effective solution for academic laboratories.

Conclusions:

• The developed semi-automated device provides a low-cost, accessible, and reproducible method for single-cell isolation.
• This innovation can enhance the capacity of academic laboratories to conduct large-scale single-cell analyses.
• The device and protocol support diverse research needs through customizable operation.
