Ultrasound Tissue Engineering Technology for Regulating Immune Microenvironment

Abstract

The immune microenvironment is critical for the occurrence, progression, and treatment of diseases. Ultrasound tissue engineering technology utilizes ultrasound and the principles of tissue engineering to repair, regenerate, and functionally reconstruct biological tissues. Ultrasound therapy is a non‐invasive treatment modality that regulates the immune microenvironment and maintains homeostasis through various characteristic effects. Ultrasound‐responsive biomaterials utilize biological properties or drug/gene delivery to regulate the immune microenvironment under ultrasound stimulation for targeted and purposeful treatment. This article comprehensively and systematically reviews advancements in ultrasound tissue engineering technology for regulating the immune microenvironment. First, the changes in the immune microenvironment at different stages of the disease is briefly illustrated. It is then reviewed the regulation of the immune microenvironment by ultrasound and ultrasound‐responsive biomaterials in five types of diseases: tumor, cardiovascular system diseases, nervous system diseases, musculoskeletal diseases, and wound. Finally, the prospects of the ultrasound tissue engineering technology for regulating the immune microenvironment is summarized.
