Purpose of the Study:
- Introduce pyTFM, an open-source software package for TFM and Monolayer Stress Microscopy.
- Optimize pyTFM for ease-of-use for researchers without specialized software expertise.
- Provide a comprehensive tool for analyzing cellular forces and stresses in 2D cell cultures.
Main Methods:
- Developed pyTFM as a standalone Python package and an add-on for ClickPoints.
- Implemented algorithms for reconstructing cell-matrix tractions and cellular stresses.
- Validated pyTFM using synthetic and experimental data from epithelial cell patches.
Main Results:
- pyTFM offers an intuitive interface for parameter setting and data analysis.
- The software allows detailed examination of input data and intermediate results.
- Accuracy and performance of pyTFM algorithms were thoroughly analyzed.
Conclusions:
- pyTFM democratizes the use of TFM and Monolayer Stress Microscopy.
- The tool facilitates the study of cellular forces and stresses in various biological contexts.
- pyTFM is well-documented and includes examples for user guidance.
