Background:

Cellular forces are vital for biological processes like tissue development and disease.
Existing force microscopy methods have limitations in throughput, real-time monitoring, and complex system applicability.

Purpose of the Study:

To introduce and validate a novel Photonic Crystal Cellular Force Microscopy (PCCFM) system.
To visualize and quantify dynamic cellular forces with high spatial and temporal resolution.

Main Methods:

Developed a PCCFM system using a conventional optical microscope and a photonic crystal substrate (silica nanoparticles in hydrogels).
Applied PCCFM to study Madin-Darby Canine Kidney (MDCK) cells and Bone Marrow Stromal Cells (BMSCs) during various cellular stages.

Main Results:

PCCFM successfully captured dynamic cellular forces during adhesion, spreading, proliferation, and osteogenic differentiation.
Distinct cellular force patterns were observed across different cellular stages, correlating with morphological changes.
Analysis of MDCK cyst fragment migration provided insights into tumor cell migration behaviors.

Conclusions:

PCCFM offers a powerful tool for real-time, high-throughput analysis of cellular biomechanics.
The system provides valuable insights into mechanisms of tumor metastasis and other disease processes.
PCCFM has the potential to guide therapeutic development for diseases involving cellular force dynamics.
