This study introduces a new statistical method to analyze cell division and death rates using CFSE dye data. The approach models cell kinetics, enabling accurate estimation of variable division and death probabilities in cell populations.

Area of Science:

  • Cellular and Molecular Biology
  • Quantitative Biology
  • Biostatistics

Background:

  • Quantifying cell division and death is crucial in biological research.
  • Carboxyfluorescein succinimidyl ester (CFSE) enables tracking of cell division in vitro and in vivo.
  • Cell proliferation exhibits stochasticity and population-level variations, leading to heterogeneity.

Purpose of the Study:

  • To develop a likelihood-based method for estimating parameters in branching process models of cell kinetics.
  • To apply this method to data from CFSE-labeling experiments.
  • To address statistical challenges in analyzing real-world CFSE data.

Main Methods:

  • Utilized branching process models to describe cell division and death dynamics.
  • Developed a likelihood-based inference framework for parameter estimation.

Related Experiment Videos

  • Validated the method using both synthetic and experimental CFSE datasets.

    • Main Results:

    • Successfully estimated cell division and death rates from CFSE data.
    • Demonstrated the method's validity on diverse datasets.
    • Proposed solutions for statistical inference and model comparison challenges with real CFSE data.

    Conclusions:

    • The presented approach accurately recovers variable division and death rates in cell populations.
    • This method is applicable to any cell population with available division tracking data.
    • Provides a robust framework for analyzing cell kinetics using CFSE experiments.
