Morphological analysis of PC12 cells incubated with uncoated-maghemite MNPs (0.25 mg/ml) 1, 3 and 5 days after NGF treatment; a Total neurite length per cell; b Number of branching points; c Number of neurites originating from soma. T test, *p < 0.05. d Fluorescent confocal images of MNP-loaded cells after 5 days of NGF treatment; Left image: α-tubulin immunostaining of cells. Middle image: fluorescent MNPs uptaken by the cells. Right image: merged image. Scale bar = 50 µm
