Figure 3From: Whole body tracking of superparamagnetic iron oxide nanoparticle-labelled cells – a rheumatoid arthritis mouse modelIn vivo dose response. A) Signal profile and B) corresponding coronal GEFI MR images relating to mMSCs labelled with 0 μg/ml (i), 1 μg/ml (ii), 5 μg/ml (iii) or 10 μg/ml (iv) and implanted within the right knee of each mouse. Red line highlights the area across which SI was measured. GEFI, gradient-echo fast imaging; mMSCs, murine mesenchymal stem cells; MR, magnetic resonance; SI, signal intensity.Back to article page
