SUMMARY:A Simple and Flexible Computational Framework for Inferring Sources of Heterogeneity from Single-Cell Dynamics
DESCRIPTION:We will discuss about “A Simple and Flexible Computational Framework for\nInferring Sources of Heterogeneity from Single-Cell\nDynamics”\, Dharmarajan et al.\, Cell Systems (2019) \nSingle-cell time-lapse data provide the means for disentangling sources of cell-to-cell and intra-cellular variability\, a key step for understanding heterogeneity in cell populations. However\, single-cell analysis with dynamic models is a challenging open problem: current inference methods address only single-gene expression or neglect parameter correlations. We report on a simple\, flexible\, and scalable method for estimating cell-specific and population-average parameters of non-linear mixed-effects models of cellular networks\, demonstrating its accuracy with a published model and dataset. We also propose sensitivity analysis for identifying which biological sub-processes quantitatively and dynamically contribute to cell-to-cell variability. Our application to endocytosis in yeast demonstrates that dynamic models of realistic size can be developed for the analysis of single-cell data and that shifting the focus from single reactions or parameters to nuanced and time-dependent contributions of sub-processes helps biological interpretation. Generality and simplicity of the approach will facilitate customized extensions for analyzing single-cell dynamics
