Stem cells hold great promise for the treatment of multiple human diseases and disorders. Tracking and monitoring of stem cells in vivo after transplantation can supply important information for determining the efficacy of stem cell therapy. Magnetic resonance imaging (MRI) combined with contrast agents is believed to be the most effective and safest non-invasive technique for stem cell tracking in living bodies. Commercial superparamagnetic iron oxide nanoparticles (SPIONs) in the aid of transfection agents (TAs) have been applied to labeling stem cells. However, owing to the potential toxicity of TAs, more attentions have been paid to develop novel SPIONs with specific surface coating or functional moieties which facilitate effective cell internalization in the absence of TAs. This review aims to summarize the recent progress in the design and preparation of SPIONs as cellular MRI probes, to discuss their applications and current problems facing in stem cell labeling and tracking, and to offer perspectives and solutions for the future development of SPIONs in this field.

“…At a high freezing rate, the ice front becomes dendritic, but since the rate of advance reached 0.43 m d −1 , faster than typical for the natural freezing environment, the discussion herein is limited to a flat ice front only. Tao et al (2005) demonstrated that not only dendritic ice, but also a planar ice front, could fragment a wastewater-sludge floc.…”

“…The maximum elongation forces acting on floc 1 throughout cycles 1-4 were 1.34, 0.748, 1.07 and 1.51 dynes, respectively, and those for floc 2 throughout cycles 1-6 were 0.428, 0.214, 0.297, 0.306, 0.347, and 0.316 dynes, respectively. Tao et al [16] indicated that the forces applied by the top stick were equal to those applied to the floc by the bottom ice front. After cycle 1, the interaction between ice and floc weakened, yielding a "minimum" maximum force applied by the stick in cycle 2.…”
