Acoustic cavitation has been widely explored for both diagnostic and therapeutic purposes. Ultrasound-induced cavitation, including inertial cavitation and non-inertial cavitation, can cause microstreaming, microjet, and free radical formation. The acoustic cavitation effects on endothelial cells have been studied for drug delivery, gene therapy, and cancer therapy. Studies have demonstrated that the ultrasound-induced cavitation effect can treat cancer, ischaemia, diabetes, and cardiovascular diseases. In this minireview, we will review the impact of ultrasound-induced cavitation on the endothelial cells such as cell permeability, cell proliferation, gene expression regulation, cell viability, hemostasis interaction, oxygenation, and variation in the level of calcium ions, ceramide, nitric oxide (NO) and nitric oxide synthase (NOS) activity. The applications of these effects and the cavitation mechanism involved will be summarized, demonstrating the important role of acoustic cavitation in non-invasive ultrasound treatment of various physiological conditions.
