Analytical flow cytometry generates vast data, challenging analysis. Multivariate data analysis and artificial neural networks (ANNs) offer solutions for identifying and clustering cell populations, improving data interpretation.

Area of Science:

  • Biotechnology
  • Data Science
  • Marine Biology

Background:

  • Analytical flow cytometry (AFC) generates high-dimensional data from multiple optical parameters at high cell rates.
  • The complexity of AFC data presents significant challenges for traditional data analysis methods.

Purpose of the Study:

  • To review the application of multivariate data analysis and pattern recognition techniques for analyzing AFC data.
  • To explore methods for identifying and clustering cell populations within complex datasets.

Main Methods:

  • Categorized approaches into identification (supervised) and clustering (unsupervised).
  • Included multivariate statistical approaches, supervised and unsupervised artificial neural networks (ANNs), and clustering methods.
  • Demonstrated techniques using AFC data from marine phytoplankton populations.

Main Results:

  • Artificial neural networks (ANNs) proved effective in managing and extracting information from large AFC datasets.
  • Identified challenges including overlapping distributions, unbounded datasets, missing parameters, and scaling issues.
  • Addressed the estimation of cell type proportions.

Conclusions:

  • ANNs enable tractable analysis of information within large AFC datasets.
  • Further research is needed to address training data acquisition for field studies and handling near-infinite cell categories.
