Endothelial progenitor cells (EPCs) have an essential role in counteracting risk factor‑induced endothelial injury and protecting against the development of vascular injury, such as myocardial infarction. Magnetic resonance imaging (MRI) was reported to be effective in tracking transplanted stem cells following cell‑labeling with superparamagnetic iron oxide (SPIO) nanoparticles. SPIO has previously been used to label and track EPCs; however, the safest concentration of SPIO for labeling EPCs on a cellular level has remained to be elucidated.

The envelope glycoprotein (Env), one of the structural proteins of FV, is an important antigen in the immunoassays, as it is highly specific. To compare the characteristics of all 15 available FV Envs, the phylogenesis, hydrophobicity, modifications, and conserved motifs were analyzed based on the Env sequences.
