Figure 3From: Formulation of novel lipid-coated magnetic nanoparticles as the probe for in vivo imagingDifferentiation status of Neuro-2a. Neuro-2a cells were treated with or without L-SPIOs (4 nmol/well) for 24 h in 10% FBS-DMEM. After L-SPIO-loading, Neuro-2a cells were then washed and exposed to 5 μM of retinoic acid for differentiation indicated by neurites outgrowth. Phase Images of Neuro-2a cells before (A, B; 100× magnification) and after (C, D; 200× magnification) retinoic acid (RA) treatment in control or L-SPIO-loaded cells as indicated.Back to article page
