In vivo tracking of the MSCs after transplantation. (a) Persistent MR hypointensities caused by MPIOs were detected at all time points at the site of injection after transplantation (arrows). (b) As time progressed, the signal gradually weakened and the area decreased. at each time point versus 3 days.
