Brief Summary:
This clinical trial aims to evaluate the use of a handheld Magnetic Particle Imaging (MPI) device for real-time, non-invasive monitoring of human umbilical cord-derived mesenchymal stromal cells (UC-MSCs) in patients with knee osteoarthritis (OA). The primary objective is to visualize and quantify the distribution, retention, and survival of SPIO (superparamagnetic iron oxide)-labeled MSCs within the joint space following intra-articular injection. By correlating MPI signal dynamics with established clinical outcomes (e.g., WOMAC, VAS scores) and anatomical MRI assessments, the study seeks to predict treatment efficacy and optimize therapeutic strategies for OA.
Current assessment of MSC therapy relies largely on MRI for structural evaluation, which has limited sensitivity for tracking early cell viability and migration. MPI offers high-contrast, radiation-free functional imaging capable of directly detecting SPIO-labeled cells. This study will enroll patients with mild-to-moderate OA (Kellgren-Lawrence grade II-III). Participants will receive a single injection of ferumoxytol-labeled UC-MSCs into the affected knee. MPI scans will be performed at multiple timepoints (day 1, 3, 7, and 30) to monitor cell homing, retention rate, and signal decay. MRI will be used in parallel to evaluate cartilage morphology and synovial changes.
The study expects to demonstrate that MPI can effectively track MSC behavior in vivo, providing a novel tool to understand cell therapy mechanisms, assess treatment response early, and potentially guide personalized OA management.
