Study of Mechanisms of Cellular Mechanosensing

点击翻译按钮获取中文摘要

There are many cells sensing mechanical forces in our body and the cells control the functions of tissues and organs to be adapted to mechanical environment. However, the mechanisms were not elucidated yet. In this study, we mainly focused on vascular endothelial cells, osteocytes and myocytes. It became clear that cell-cell and focal adhesions and cytoskeletons such as stress fiber are working as mechanosensors and some proteins in cytoplasm were identified as signal messengers. Mechanical forces were also playing important roles in organogenesis such as valve formation in cardiovascular system.
