The use of nanometer and micrometer-sized superparamagnetic iron oxide particles as cellular contrast agents allows for the noninvasive detection of labeled cells on high-resolution magnetic resonance images. The development and application of these techniques to neurologic disorders is likely to accelerate the development of cell transplantation therapies and allow for the detailed study of in vivo cellular biology. This review summarizes the early development of iron oxide-based cellular contrast agents and the more recent application of this technology to noninvasive imaging of cellular transplants. The ability of this technique to allow for the noninvasive detection of in vivo transplants on the single-cell level is highlighted.
使用纳米和微米级超顺磁性氧化铁颗粒作为细胞造影剂,能够在高分辨率磁共振图像上对标记细胞进行无创检测。这些技术在神经系统疾病中的开发与应用,可能会加速细胞移植疗法的发展,并有助于对体内细胞生物学进行详细研究。本综述总结了基于氧化铁的细胞造影剂的早期发展情况,以及该技术在细胞移植无创成像方面的最新应用。重点介绍了该技术在单细胞水平上对体内移植进行无创检测的能力。
