In vitro MR images of CD81-MPIO. (a) T2-weighted imaging of the control cells and PMS-stimulated cells incubated with various concentrations of CD81-MPIO (left panel) or IgG-MPIO (right panel) at 1 × 105, 1 × 106, or 1 × 107 particles. (b) The T2 relaxation time of the control cells and the PMS-stimulated after incubation with CD81-MPIO or IgG-MPIO.
