    Area of Science:

    • Cell biology
    • Developmental biology
    • Computational biology

    Background:

    • Epithelial cell sheets form tissues with interconnected cells via membrane junctions.
    • These tissues resemble planar graphs, with cells as faces.
    • Accurate cell tracking is crucial for understanding tissue dynamics.

    Purpose of the Study:

    • To introduce a novel method for tracking cells in connected tissue sheets.
    • To leverage the planar graph structure of tissues for improved cell tracking.
    • To provide a robust tool for automated cell analysis in developmental biology.

    Main Methods:

    • Developed a deformable graph tracking method for cell sheets.
    • Modeled tissues as planar graphs where cells are faces.
    • Utilized a coupled model where vertices and edges inform each other for tracking.

    Main Results:

    • The deformable graph method demonstrated superior performance compared to four reference algorithms.
    • Achieved accurate cell tracking across all image frames and diverse conditions.
    • Showed robustness to variations in image intensity and cell shape.

    Conclusions:

    • The proposed method offers accurate and robust cell tracking for connected tissue sheets.
    • This tool can significantly advance automated cell analysis in developmental biology.
    • Facilitates the study of mechanisms behind cell-shape changes during development.
