In this paper we demonstrate that contactless high-frequency ultrasound microbeam stimulation (HFUMS) is capable of eliciting cytoplasmic calcium (Ca2+) elevation in human umbilical vein endothelial cells (HUVECs) and the associated mechanisms were highly correlated with those of shear force induced cytoplasmic Ca2+ elevation. Ca2+ and cytoplasmic Ca2+stores were involved in the Ca2+ elevation. These results… Continue reading In this paper we demonstrate that contactless high-frequency ultrasound microbeam stimulation
