Endothelial differentiation of mesenchymal stem cells induced by the combined mechanical stimulation of wall shear stress and cyclic strain by Naoya SAKAMOTO, Kohei TATEBAYASHI, Hiromi MIYOSHI

“…Differentiation of mesenchymal stem cells (MSCs) into vascular endothelial cells has been demonstrated for application in cardiovascular regenerative medicine. In this study, we evaluated the effect of the combined mechanical stimuli of wall shear stress (SS) and cyclic strain (CS), mimicking hemodynamic conditions of arteries, on endothelial differentiation of MSCs. …”

Proposal of an unconstrained measurement of instantaneous heart rate using tactile sensors by Yudai OGISHI, Toshiharu MUKAI

“…This fluctuation is induced by various causes, and it is said that, by analyzing the fluctuation, useful information on the health state such as the stress index and prognosis of cardiovascular system can be obtained. However, because heart rates are usually measured with cumbersome sensor devices or electrodes, the measurement of instantaneous heart rate, which has equivalent information to heart rate variability, is also difficult to be conducted on a daily basis. …”
