MSC adipogenic differentiation assay. a–c Oil Red O cytochemical analysis of differentiated MSC monolayers in light microscopy, with in order to evidence the formation of intracellular lipid vesicles. These vesicles were seen in control cells (a), in γ-Fe2O3-DMSA labeled cells, (b) and in Au-DMSA labeled cells (c). d Quantification of Oil Red O incorporated in monolayers of differentiated and non-differentiated MSC, with no significant difference between control and experimental groups (p > 0.05).
