Following in vivo prelabeling of host macrophages with ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles, it was shown that their magnetic resonance (MR) imaging–visible migration into knee implants of scaffolded adipose-derived stem cells (ADSCs) undergoing apoptosis can serve as a surrogate marker of stem cell death.
在用超顺磁性氧化铁(USPIO)纳米粒子对宿主巨噬细胞进行体内预标记后,研究表明,它们的磁共振(MR)成像可见迁移到支架脂肪来源干细胞(ADSCs)凋亡的膝关节植入物中,可以作为干细胞死亡的替代标志物。
