Project description:Embryonic stem cells are pluripotent and possess the ability to differentiate into numerous lineages during the developmental process. In similarity to embryonic stem cells, human induced pluripotent stem cells (iPSCs) possess the potential to differentiate into multiple lineages making them an excellent research tool. We generated iPSCs from multiple donors and also differentiated iPSCs from these donors into human neural progenitor cells (NPCs). We used human transcriptome arrays to detail the programme of gene expression underlying NPC induction and identified distinct classes of up-regulated genes during this process. Total RNAs were extracted from human induced pluripotent stem cells and induced pluripotent stem cell-derived neural progenitor cells. Their gene expression profiles were investigated using the Affymetrix GeneChip Human Transcriptome Array 2.0 platform.
Project description:We have generated isogenic induced pluripotent stem cell lines by reprogramming human fibroblasts from patients carrying the LRRK2 G2019S mutation with subsequent zinc finger nuclease - mediated targeted correction of the diseased allele. These iPS cell lines were differentiated for 30 days using a direct differentiation protocol towards midbrain dopaminergic neurons (mDANs). Isogenic human iPS cells carrying the LRRK2 WT and G2019S locus were differentiated to dopaminergic neurons to detect gene expression changes associated with mutated LRRK2.
