Description
Human prostate CWR22 OT-tumor cells were prospectively purified for expression of various stem cell markers (TRA-1-60/CD151/CD166/EpCAM/CD44/2-Integrin). Unsorted total tumor cells or the additional marker positive cells that do not manifest stem-like characteristics were used as control. All these cells were subjected to molecular profiling of total RNA expression and the fold change data are tabulated according to S/TFE of the purified cells in relation to their control.

Description
We have developed efficient protocols for the derivation of mesenchymal precursors from hESCs. While previous protocols were based on mesodermal induction via co-culture of hESCs on OP9 mouse stroma (Barberi et al., PLoS Biology, 2005), our recent work shows the derivation of hESC derived mesenchymal precurors under feeder-free conditions. The data presented here show a large and highly signficant overlap in global gene expression profiles between hESC derived mesenchymal precursors derived under feeder-free conditions with those derived via OP9 co-culure and mesenchymal precurosrs isolated directly from the adult bone marrow.

Description
Here we present a strategy to adapt hESCs to high-throughput screening (HTS) conditions, resulting in an assay suitable for the discovery of small molecules that drive hESC self-renewal or differentiation. Use of this new assay has led to the identification of several currently marketed drugs and natural compounds promoting short-term hESC maintenance and compounds directing early lineage choice. Global gene expression analysis upon drug treatment reveals overlapping and novel pathways correlated to hESC self-renewal and differentiation. Our results demonstrate feasibility of hESC-based HTS and enhance the available repertoire of chemical compounds for manipulating hESC fate.

Description
The use of pluripotent stem cells in regenerative medicine and disease modeling is complicated by the variation in differentiation properties between lines. In this study, we characterized 13 human embryonic stem cell. (hESC) and 26 human induced pluripotent stem cell (hiPSC) lines to identify markers that predict neural differentiation behavior. At a general level, markers previously known to distinguish mouse ESCs from epiblast stem cells (EpiSCs) correlated with neural differentiation behavior. More specifically, quantitative analysis of miR-371-3 expression prospectively identified hESC and hiPSC lines with differential neurogenic differentiation propensity and in vivo dopamine neuron engraftment potential. Transient KLF4 transduction increased miR-371-3 expression and altered neurogenic behavior and pluripotency marker expression. Conversely, suppression of miR- 371-3 expression in KLF4-transduced cells rescued neural differentiation propensity. miR-371-3 expression level therefore appears to have both a predictive and a functional role in determining human pluripotent stem cell neurogenic differentiation behavior.

Description
The development of the central nervous system (CNS) depends on the orchestrated generation of neurons and glia from neural stem cells (NSCs). Although NSCs generate both cell types, they are produced sequentially as neurons are born first and glia later. In humans, this timing is extremely protracted and the underlying mechanisms remain unknown. Deriving glial cells such as astrocytes from human pluripotent stem cells requires 3-6 months of differentiation, greatly impeding their use in human disease modeling and regenerative medicine. Here, we report that expression of the transcription factor nuclear factor IA (NFIA) is sufficient to trigger glial competency in highly neurogenic NSCs and enables the derivation of human astrocytes within 10-12 days. NFIA-induced astrocytes are functional and shown to promote synaptogenesis, protect neurons and generate calcium transients. The mechanism of NFIA-induced glial competency involves rapid but reversible chromatin remodeling, demethylation of the GFAP promoter and a striking effect on the cell cycle. NFIA titration and pharmacological studies indicate that acquisition of a glial-compatible G1 length is critical for achieving glial competency. Our results offer mechanistic insights into human glial competency and enable the routine use of astrocytes for studying human development and disease. Overall design: The timecourse consists of 4 timpoints. Day 0 (d0) represents neurogenic LTNSCs, day 3 (d3) represents overexpression of NFIA with doxycycline and cells were harvested in bulk, day 6 (d6) represents cells sorted for CD44 while NFIA is overexpressed, day 9 (d9) represents CD44+ sorted cells replated in culture without the addition of doxycyline to downregulate NFIA and day 12 (d12) represents the same cultures in d9, but with 3 additional days of no doxycycline treatment. Each timepoint has a minimum of 3 biological replicates. Rosette cells (H9 d0) and neurons (Dapt) were profiled as controls where rosettes were one sample and neurons were performed in duplicate.

Description
Familial Dysautonomia is a genetic disease, however patietns with the same genotype present with mild or severe forms of the disease. We used the pluripotent stem cell technology to capture the differences in disease severity in vitro during neurodevelopment as well as during maintanance of the cells, showing developmental and degenerative phenotypes. RNA seq. analysis of the groups confirmed those diffferences. Overall design: Analysis of RNA from PSC-derived neural crest cells from severe FD, mild FD and healthy patients

Description
We have generated expression profiles of induced pluripotent stem cells (iPSCs) and iPSC-derived neural crest populations from Familial Dysautonomia patients. These profiles were compared to a normal iPSC line that does not harbor the IKBKAP mutation. Overall design: All cell types were differentiated from patient derived iPSCs. Bulk iPSCs were harvested for RNA and the neural crest populations were sorted on day 18 for p75/HNK1 before RNA isolation.
