Functional characterizations of the derived microglia-like cells. (A) mRNA gene expression of (i) TNF-α, IL-6, and (ii) MMP2, MMP3 after Aβ42 oligomer stimulation for 72 hours (n = 3). *Indicates p < 0.05 for the different test conditions. (B) Quantification of micron-sized particles of iron oxide (MPIO) phagocytosis by microglia-like cells and iPSC-NPC (neural progenitor cells) and iPSC-EC (endothelial cells) controls (called as iNPC and iEC). Black line: negative control; red line: cells with MPIO. (C) The cytokine secretion of microglia-like cells (n = 3), stimulated by Aβ42 oligomers (0.5 µM), Lipopolysaccharides (LPS) (100 ng/ml), and dexamethasone (1 µM) for 72 hours as determined by ELISA assays. (i) PGE2; (ii) TGF-β1 and (iii) VEGF-A. *Indicates p < 0.05 for the test conditions compared to the control.
