Background:

Single-cell RNA sequencing generates vast datasets requiring advanced analytical tools.
Understanding cellular differentiation dynamics and integrating cell atlas data are critical challenges.

Purpose of the Study:

To introduce single-cell Type Order Parameters (scTOP), a novel statistical framework for quantifying cell identity.
To demonstrate scTOP's utility in cell classification, trajectory visualization, and engineered cell assessment.

Main Methods:

scTOP employs a physics-inspired, statistical approach to quantify cell identity based on a reference cell type basis.
The method operates without requiring feature selection, statistical fitting, or dimensionality reduction techniques.

Main Results:

scTOP accurately classifies cells and visualizes developmental trajectories across human and mouse datasets.
Analysis of mouse lung data identified a transient hybrid alveolar cell population.
scTOP visualizations confirmed multi-lineage differentiation from single hematopoietic clones and assessed cell transplantation fidelity.

Conclusions:

Physics-inspired order parameters offer a powerful tool for analyzing cellular differentiation.
scTOP provides an effective and accessible method for characterizing both endogenous and engineered cells.
The scTOP Python package facilitates its widespread application in single-cell data analysis.
