Project description:There are a total of four samples each for this analysis. Each sample consists of the cells grown on three 10 cm culture plates. Each plate should have 2x106 cells for a total of 6x106 cells per sample when all three plates are combined. The first sample is undifferentiated human embryonic stem cells, the second sample is human glutamatergic neurons derived from those human embryonic stem cells, the third sample is undifferentiated human induced pluripotent stem cells and the fourth sample is human glutamatergic neurons derived from those human induced pluripotent stem cells.
Project description:This SuperSeries is composed of the following subset Series: GSE21243: Expression data from undifferentiated human induced pluripotent stem cells GSE21244: Expression data from undifferentiated human pluripotent stem cells Refer to individual Series
Project description:Expression data from undifferentiated human induced pluripotent stem cells total RNA was isolated from undifferentiated induced pluripotent stem cells grown in standard HESC growth conditions on mouse embryonic fibroblast feeder layer.
Project description:Expression data from undifferentiated human embryonic stem cells and induced pluripotent stem cells total RNA was isolated from undifferentiated pluripotent stem cells grown in standard HESC growth conditions on mouse embryonic fibroblast feeder layer.
Project description:We report the secreted microRNAs from extracellular vesicles released from (i) cardiomyocytes, (ii) cardiac fibroblasts, (iii) endothelial cells differentiated from identical lines of normal human induced pluripotent stem cells and (iv) undifferentiated induced pluripotent stem cells.
Project description:The use of human pluripotent stem cells (hPSCs) in cell therapy is hindered by the tumorigenic risk from residual undifferentiated cells. Here we performed a high-throughput screen of over 52,000 small molecules, and identified 15 highly selective cytotoxic inhibitors of hPSCs (PluriSIns). Cellular and molecular analyses revealed that the most selective compound, PluriSIn #1, is a pluripotent-specific inhibitor of stearoyl-coA desaturase (SCD1), the key enzyme in the biosynthesis of monounsaturated fatty acids (MUFA). SCD1 inhibition in hPSCs induced ER stress, protein synthesis attenuation, and apoptosis of these cells, revealing that MUFA biosynthesis is crucial for their survival. PluriSIn #1 was also cytotoxic toward the ICM cells of mouse embryos, indicating that the dependence on SCD1 is inherent to the pluripotent state. Finally, application of PluriSIn #1 prevented teratoma formation from tumorigenic undifferentiated cells. Our novel method to eliminate undifferentiated cells from culture should thus increase the safety of hPSC-based treatments. Expression data from undifferentiated and differentiated human embryonic stem cells. Total RNA was isolated from undifferentiated human pluripotent stem cells grown on matrigel with mTeSR1 medium, or from early endodermal progenitor cells differentiated from human embryonic stem cells.
