Gene Expression Modulation by Ultrasound-Responsive Biocatalytic 3D Scaffolds for Controlled Osteosarcoma Cell Elimination and Rat Cranial Bone Regeneration


ABSTRACT: Sonodynamic therapy (SDT) offers high efficiency and controllable precision in tumor eradication, while smart enzyme-mimetic materials enable pH-dependent switching between ROS generation and scavenging. Herein, we present HS-ICTO, a 3D-printed scaffold with ultrasound-triggered activation and microenvironment-responsive enzyme-mimetic properties, designed for spatiotemporally controlled therapeutic applications. The HS-ICTO scaffold synergistically enhances tumor elimination via TME-responsive ROS generation coupled with SDT effects, while switching to ROS scavenging in physiological conditions to protect stem cells. We conducted RNA sequencing on human osteosarcoma 143B cells treated with conventional scaffold (HS), HS-ICTO, and HS-ICTO + ultrasound (US), and performed comparative transcriptomic analysis of tissue cells in rat calvarial defect repair models implanted with HS versus HS-ICTO scaffolds.
