Abstract Superparamagnetic iron oxide nanoparticles have been widely used for cell labeling in preclinical and clinical studies, to improve labeling efficiency, particle conjugation and surface modifications are developed, but some modified SPIONs exert side-effect on physiological activity of cells, which cannot be served as ideal cell tracker. In this study, amine-modified silica-coated SPIO (SPIO@SiO2NH2, SPIO@S-N) nanoparticles were used to label bone marrow derived mesenchymal stem cells (BMD.

MSCs), then the stem cell potentials were evaluated. It was found BM-MSCs could be efficiently labeled by SPIO@S-N nanoparticles. After labeling, the BMMSCs viability kept well and the migration ability increased, but the osteogenesis and adipogenesis potentials were not impaired. In steroid associated osteonecrosis (SAON) bone defect model, stem cell implantation was performed by injection of SPIO@SN labeled BM-MSCs into marrow cavity locally, it was found the SPIO positive cells homed to the periphery of defect region in control group, but were recruited to the defect region in poly lactic-coglycolic acid/tricalcium phosphate (PLGA/TCP) scaffold implantation group. In conclusion, SPIO@S-N nanoparticles promoted migration while retained proliferation and differentiation ability of BM-MSCs, implying this kind of nanoparticles could be served not only an ideal tracking marker but also an accelerator for stem cell homing during tissue repair.

Introduction Mesenchymal stem cells (MSCs) derived from bone marrow are multipotent stromal cells that can differentiate into a variety of cell types, including adipocytes, osteocytes, chondrocytes and myocytes (Matthay et al. 2017; Pittenger et al. 1999; Zhao et al. 2011). These cells play a vital role in the repair and regeneration of various tissues and organs throughout the human body (Xi et al. 2013). Many studies show that
