Project description:Transcriptome profile was obtained from a set of human embryonic stem cell (hESCs) line (WA09: H9) with different passage numbers (P1: 40s, P2: 100s, P3: 200s, P4: 300s passage). Culture adaptation occurs in hESCs during repeated in vitro culture to acquire ‘survival advantage’ to be highly resistant to various stresses. In special, difference in gene expression profile of cell death or apoptotic gene signature was evident between P1/P2 and P3/P4 hESCs.
Project description:In this study, we generated wildtype H9 hESC derived cardiomyocytes (CM) and neural stem cells (NSC) by in vitro differentiation. Global gene expression profiles were compared among undifferentiated H9 hESC and the derived CM and NSC. Comparison of global gene expression profiles of undifferentiated H9 hESC and the derived CM and NSC populations.

Project description:Human embryonic stem cells (WiCell H9 passage 52) were differentiated following the Novocell protocol (D'Amour et al. Nature Biotechnology, 2005). The two biological replicates (Trial 15 and Trial 16) were analyzed by Real-Time PCR utilizing TaqMan Low Density Array Cards that have been customized for a set of 46 genes specific for endoderm and pancreatic gene expression.
Project description:Human mesenchymal stem cells are expected to be a useful tool for cellular therapy. We used microarrays to detail the gene expression profiles and selected candidate biomarkers that indicate the culture stage of the cells. Experiment Overall Design: Human mesenchymal stem cells were cultured and subjected to RNA extraction and hybridization on microarrays. Cell cultures in passage numbers 5, 7, 9, 13, 14, 21, and 28 of lot#4F1560 were subjected to the microarray analysis.
Project description:Genetic mutations on leucine-rich repeat kinase 2 (LRRK2) have been associated with an increased risk of Parkinson's disease. The Gly2019Ser (G2019S) mutation on LRRK2 gene is a relatively common cause of familial Parkinson's disease in Caucasian population. In this study, we generated H9 hESC harboring LRRK2 (G2019S) mutation by gene knockin. Wildtype and LRRK2 mutant hESC were differentiated into NSC using a chemically defined protocol.
Project description:Use of single-cell transcriptomics to measure how well medium spiny projection neurons, derived from human ESC, recapitulate human striatal development in vivo. This in vitro single-cell dataset was derived after exposing hESC lines (H9) to a novel striatal differentiation protocol and performing single-cell RNA-seq after 15 days and 25 days of differentiation.
Project description:Extracellular vesicles (EV) are secreted by nearly every mammalian cell type and contain a wealth of bioactive cargo capable of modulating target cell physiology and function though a variety of paracrine signaling mechanisms (Leavitt et al., 2019). Human embryonic stem cell (hESC)-derived extracellular vesicles (hESC-derived EV), were extracted from the hESC line H9 (WA09 Wicell Research Institute, Inc., Madison, WI). We analyzed the bioactive protein cargo to identify components that help to resolve radiation-induced injury to the lung in mice when injected in vivo.
