We have read with great interest the paper of Ketkar-Atre et al,1 in which they have developed a new way of tracking stem cells after transplantation using a magnetic resonance imaging (MRI)-based method. They have proven using high resolution electron microscopy that various types of undifferentiated cells, also known as stem cells, have a differentiation uptake of iron oxide nanoparticles according to their size and proliferation rate. Due to its super-paramagnetic properties, iron oxide is slowly finding its way from the laboratory to the clinic. When combined with MRI, it can very efficiently track a stem cell in vivo, as in the case of autologous transplantation,2,3 but also for other conditions such as Duchenne muscular dystrophy.
