Figure Lengend Snippet: B7H6 expression is maintained in motoneurons differentiated from iPS-derived neural progenitor cells. (A) B7H6 (NCR3LG1) transcription was assessed by qPCR analysis using cDNA from the indicated cells, displaying relative expression using GNB2LI as housekeeping control. The tumor cell lines HCT15 and MDA.MB.231 have been included as B7H6+ and B7H6− controls, respectively. The results are normalized and represent 3 or more independent triplicate experiments. Neurons were generated from iPS-derived NPCs, and their phenotype was documented by (B) phase contrast microscopy demonstrating dendritic morphology, and (C) qPCR analysis for the neuronal markers NeuN (RBFOX3), MAP-2 (MAP2), class III β-tubulin (TuJ1; gene TUBB3), and synaptotagmin (SYT1), as indicated. NPC phenotype was defined by downregulation of the pluripotency marker Oct4 (POU5F1) and concomitant upregulation of nestin (NES). Expression was calculated using β-actin as an internal control. Error bars indicate SD based on 1 triplicate experiment.
