Background:

Studying cellular responses to mechanical stimuli is crucial for understanding physiological processes.
Existing methods for applying mechanical strain to cells often lack real-time imaging capabilities or precise control.

Purpose of the Study:

To develop a multiarray microchip platform with integrated real-time imaging for applying controlled mechanical strains to monolayer cell cultures.
To investigate acute and long-term cellular morphological changes under mechanical stress.

Main Methods:

Cells were cultured on an 8-µm thick membrane within a microchip.
A programmable pneumatic control system actuated elastomeric layers and a glass coverslip to apply mechanical strain.
Real-time imaging and post-stretching immunofluorescence imaging were employed.
