Cell tracking via MRI has drawn much attention recently for its sensitive, deep, and real-time properties and high spatial resolution. In a previous chapter, the labeling and tracking of superparamagnetic iron oxide (SPIO)-nanoparticle-loaded stem cells have been well summarized (Sykova et al., Methods Mol Biol 750:79-90, 2011). Thus, in this chapter, we will mainly focus on the tracking of SPIO-nanoparticle-labeled mouse dendritic cells by MRI and provide a detailed protocol for cell labeling and in vivo tracking by a clinical 3.0T MRI scanner. Of note, this protocol is also suitable to be applied on other types of cells.
细胞示踪的磁共振成像是一种新型的细胞示踪方法,具有灵敏度高、能进行深层和实时检测、空间分辨率高等特点,目前已受到广泛关注。在前面的章节中,已经对超顺磁性氧化铁(SPIO)纳米颗粒标记的干细胞的标记和示踪进行了很好的总结(Sykova 等人,Methods Mol Biol 750:79-90, 2011)。因此,在本章中,我们将主要关注 SPIO 纳米颗粒标记的树突状细胞的 MRI 示踪,并提供一种使用临床 3.0T MRI 扫描仪进行细胞标记和体内示踪的详细方案。值得注意的是,该方案也适用于其他类型的细胞。
