Mesenchymal stem cells (MSCs) using ferumoxides–PLL. Cells were labeled for 48 h (a, b) or 24 h (c) with 25 mg Fe/ml Feridex and 375 ng/ml PLL. DAB-enhanced Prussian blue stain of labeled human (a), porcine (b), and canine (c) MSCs show an efficient intracellular uptake of particles into endosomes that is nonspecific across species.
