We herein report a comparative study of mesenchymal stem cell (MSC) labeling using spherical superparamagnetic iron oxide (SPIO) nanoparticles containing different coatings, namely, organosilica, dextran, and poly(ethylene glycol) (PEG). These nanomaterials possess a similar SPIO core size of 6-7 nm. Together with their coatings, the overall sizes are 10-15 nm for all SPIO@SiO₂, SPIO@dextran, a...

PURPOSE The purpose of our study was to validate diffusion-weighted MRI (DWI) before and after superparamagnetic iron oxide (SPIO) injection for assessment of hepatic metastases. MATERIALS AND METHODS Eighty-six hepatic metastases (size range, 0.3-4.7 cm; mean, 1.5 cm) verified pathologically or by follow-up imaging studies in 22 consecutive patients (17 men and 5 women; 44-83 years; mean age...

PURPOSE To compare the cellular uptake efficiency and cytotoxicity of aminosilane (SiO(2)-NH(2))-coated superparamagnetic iron oxide (SPIO@SiO(2)-NH(2)) nanoparticles with three other types of SPIO nanoparticles coated with SiO(2) (SPIO@SiO(2)), dextran (SPIO@dextran), or bare SPIO in mammalian cell lines. MATERIALS AND METHODS Four types of monodispersed SPIO nanoparticles with a SPIO core s...

PURPOSE: In the previous study, it has been reported that liver and spleen uptake of superparamagnetic iron oxide (SPIO) was significantly decreased at SPIO-enhanced MR imaging in cirrhotic patients. However, we have often encountered the cases with increased uptake of SPIO in the spleen in patients with cirrhosis. The purpose of this study was to clarify whether the uptake of SPIO in the splee...

background susceptibility-weighted imaging (swi) is extremely sensitive in the detection of superparamagnetic iron oxide (spio) nanoparticle-labeled cells. however, no study has compared molecular imaging for stem cell detection using swi and other mri pulse sequences. objectives this study aims to assess the sensitivity of swi in detecting spio nanoparticle-labeled, human bone marrow-derived m...

Superparamagnetic iron oxide (SPIO) nanoparticles generate superparamagnetism, thereby resulting in an inhomogeneous local magnetic field, which shortens the T2 value on magnetic resonance imaging (MRI). The purpose of the present study was to use MRI to track bone marrow mesenchymal stem cells (BMSCs) labeled with SPIO in a rat model of myocardial infarction. The BMSCs were isolated from rats ...

BACKGROUND Articular cartilage has very limited intrinsic regenerative capacity, making cell-based therapy a tempting approach for cartilage repair. Cell tracking can be a major step towards unraveling and improving the repair process of these therapies. We studied superparamagnetic iron oxides (SPIO) for labeling human bone marrow-derived mesenchymal stem cells (hBMSCs) regarding effectivity, ...

Superparamagnetic iron oxide nanoparticles (SPIO NPs) have a wide range of biomedical applications such as in magnetic resonance imaging, targeting, and hyperthermia therapy. Aggregation of SPIO NPs can occur because of the hydrophobic surface and high surface energy of SPIO NPs. Here, we developed a facile method to encapsulate SPIO NPs in amphiphilic biodegradable polymer. Anionic biodegradab...
