Area of Science:

  • Metabolomics
  • Single-cell biology
  • Bioinformatics

Background:

  • Metabolomics provides insights into cellular chemical processes.
  • A significant trend in research is the shift from bulk metabolomics to single-cell metabolomics (SCM).
  • A comprehensive workflow for SCM data analysis is currently lacking.

Purpose of the Study:

  • To develop the first comprehensive and in-depth workflow for analyzing single-cell metabolomics (SCM) data.
  • To update the existing MMEASE tool, originally for bulk metabolomics, to MMEASE 2.0 for SCM analysis.
  • To provide a complete analytical pipeline for modern SCM research.

Main Methods:

  • MMEASE 2.0 was developed as a comprehensive workflow for SCM data analysis.
  • The workflow encompasses SCM data processing, cellular heterogeneity analysis, high-resolution metabolite annotation, and cell-based biological interpretation.
  • MMEASE 2.0 integrates a wide variety of analytical methods for each step of SCM analysis.

Main Results:

  • MMEASE 2.0 provides a complete, sequential workflow for SCM data analysis.
  • The tool incorporates the broadest range of methods compared to existing SCM analysis tools.
  • Validation through case studies on benchmark data demonstrated the originality and functionality of MMEASE 2.0.

Conclusions:

  • MMEASE 2.0 is a unique and indispensable tool for comprehensive and in-depth analyses of single-cell metabolomics data.
  • The workflow facilitates a deeper understanding of cellular metabolic heterogeneity and function.
  • MMEASE 2.0 is freely accessible, supporting advancements in the field of SCM research.
