Abstract
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.
