We present here a platform for controlling cellular microenvironments and functionalities. The aim is to provide physiologically relevant culture conditions and to control and regulate the functions of cells.
The system includes modules for environment measurement and control [1-3], mechanical cell stimulation [4-5], and cell imaging and analysis  together with bicompatible, flexible, and cell-friendly materials as presented in Figure 1. The set-up of the system can be changed to meet the requirements of the physiological study. For example, the system can be used for a long-term stem cell culturing outside an incubator and to study the behavior of cells to different environment conditions.
We used beating cardiomyocytes to demonstrate the capability of the platform in two experiments, where we studied the relationship between the beating rate and 1) culture temperature , 2) hypoxia conditions .
