Background:

Micropattern traction microscopy (MTM) offers control over single-cell and cell-cluster shapes.
It enables traction force measurements by patterning contact zones at the micrometer scale.
MTM is applicable to diverse cell types like endothelial cells, fibroblasts, and epithelial cells.

Purpose of the Study:

To review the evolution of techniques for printing extracellular matrix proteins in regular dot arrays on hydrogels.
To describe methods for generating micropatterned dots for cell shape control and traction force microscopy.
To present computational approaches for analyzing cell-generated traction fields.

Main Methods:

Review of microcontact printing and subtractive patterning techniques for creating micropatterned hydrogels.
Description of pattern transfer from rigid coverslips to soft hydrogels during gelation.
Overview of computational image analysis for traction force mapping.

Main Results:

Evolution from multi-step to single-step subtractive patterning for simplified user application.
Demonstration of micropatterns enabling single focal adhesion formation and hydrogel deformation.
Development of computational tools for analyzing cell traction forces.

Conclusions:

Advancements in micropatterning techniques have refined cell shape control and traction force measurements.
Computational analysis tools are crucial for interpreting cell mechanics data from MTM.
This review provides a comprehensive overview of MTM techniques and analysis for researchers.
