Project description:Human pluripotent stem cells (hPSCs) have the potential to generate any human cell type, and one widely recognized goal is to make pancreatic β cells. To this end, comparisons between differentiated cell types produced in vitro and their in vivo counterparts are essential to validate hPSC-derived cells. Genome-wide transcriptional analysis of sorted insulin-expressing (INS(+)) cells derived from three independent hPSC lines, human fetal pancreata, and adult human islets points to two major conclusions: (i) Different hPSC lines produce highly similar INS(+) cells and (ii) hPSC-derived INS(+) (hPSC-INS(+)) cells more closely resemble human fetal β cells than adult β cells. This study provides a direct comparison of transcriptional programs between pure hPSC-INS(+) cells and true β cells and provides a catalog of genes whose manipulation may convert hPSC-INS(+) cells into functional β cells

Project description:We compare transcriptomic profiles of human induced pluripotent stem cells (iPSCs), motor neurons (MNs) in vitro differentiated from iPSCs or human ESCs containing a HB9::GFP reporter for MNs, and human fetal spinal cords. The purpose of this comparison is to assess the extent of molecular similarities between in vitro differentiated MNs and in vivo fetal or adult spinal cord MNs. Data for adult spinal cord MNs are published from other studies: GSE3526, GSE19332, GSE20589, and GSE40438. Human induced pluripotent stem cells, pluripotent stem cell derived motor neurons, and fetal spinal cords for RNA extraction and hybridization on Affymetrix arrays.

Project description:Human pluripotent stem cells were differentiated into hematopoietic progenitors, which were then re-specified using defined transcription factors to resemble hematopoietic stem cells (HSC) We used microarrays to establish the similarity between converted cells and purified human HSCs. The samples analyzed were: starting embryoid body progenitors, transcription factor-converted cells, and primary HSCs and progenitors from fetal liver and cord blood. All samples were flow sorted for CD34+ and CD38- to compare across a similar population of primitive cells.

Project description:The corneal endothelium is composed of a monolayer of corneal endothelial cells (CECs), which is essential for maintaining corneal transparency. Human embryonic stem cells (hESCs) hold the promise of providing an abundant donor source for generating CEC cells for cell replacement therapies. Here we demonstrate that CEC-like cells can be efficiently derived from human ESCs. In addition, we performed global gene expression profiling of stem-cell-derived CEC cells, incorporating with adult CEC cells, fetal CEC cells and other human tissue type data. Our data indicate that hESC-derived CEC-like cells closely resemble human fetal CEC cells.

Project description:The remarkable differentiation capacity of pluripotent stem cells into any adult cell types have enabled researchers to model human embryonic development and disease process in dishes, as well as deriving specialized cells for replacing damaged tissues. Type 1 diabetes is a degenerative disease characterized by autoimmune destruction of the insulin-producing beta islet cells in the pancreas. Recent advances have led to the establishment of different methods to direct differentiation of human or mouse pluripotent stem cells toward beta cell lineages. However, existing strategies have not yet succeeded in generating fully functional beta cells in vitro. Thus, it remains a major challenge to identify novel regulators of beta cell differentiation and maturation, and the islet-specific genetic and epigenetic regulatory networks are logical targets. To obtain a comprehensive view of the microRNA expression pattern during in vitro directed differentiation of hPSC into pancreatic beta islet cells, we collected 16 samples of 6 stages of differentiated derivatives, 2 samples of human fetal pancreas and 5 samples of purified human beta islet cells for analysis. With these samples, we performed genome-wide microRNA expression profiling using the Illumina Human v2 MicroRNA Expression BeadChips (1,146 assays).
