We developed an automatic method to track cell shape and motion in 3D microscopy, crucial for understanding cell migration in biology and disease.

Area of Science:

  • Cell biology
  • Biophysics
  • Bioimaging

Background:

  • Cellular shape and motion are vital for biological processes like immune response, development, and cancer.
  • Quantitative analysis of cell dynamics requires robust segmentation and tracking methods.

Purpose of the Study:

  • To present a fully automatic method for segmenting and tracking cells in dynamic 3D microscopy data.
  • To enable quantitative analyses of cellular shape and motion.

Main Methods:

  • The method employs multiple active surfaces with or without edges.
  • It incorporates a penalty for overlaps and a volume conservation constraint for accurate cell/cell boundary outlining.
  • The approach is designed for robustness against low signal-to-noise ratios and handles complex cell behaviors.

Main Results:

  • Quantitative validation was performed using synthetic images.
  • The method demonstrated effectiveness in handling multiple cells, including those that touch, divide, or change volume.
  • Successful applications to real biological data were shown.

Conclusions:

  • The developed method provides a robust and automatic solution for analyzing cell migration and deformation.
  • It facilitates quantitative insights into cellular dynamics from 3D microscopy, applicable to various biological contexts.
