(Submitter supplied) Human embryonic stem (hES) cells have unique features: self-renewal ability and pluripotency. They can be continuously cultured in undifferentiated state and give rise to cells and tissues of all three germ layers. Thus hES cells provide a resource not only for cell replacement therapy but also for studying human developmental biology. However, much work needs to be done to understand the molecular mechanisms responsible for the maintenance of the undifferentiatiation state and the differentiation process of human embryonic stem cells. more...

(Submitter supplied) MicroRNAs (miRNAs) are noncoding RNAs of approximately 22 nucleotides in length that usually suppress the translation of target messenger RNAs (mRNAs) through partial complementarity to the 3¡¦ untranslated region (3¡¦ UTR) of protein-coding mRNAs in animals. However, there is increasing evidence that miRNAs can also reduce the steady-state levels of their target mRNAs in animals. In this investigation, both miRNA and mRNA profiles from the undifferentiated human embryonic stem cell line hES-T3 (T3ES), hES-T3 derived embryoid bodies (T3EB) and hES-T3 differentiated fibroblast-like cells (T3DF) were quantitatively determined. more...

(Submitter supplied) Human embryonic stem (hES) cells have the capacities to propagate for extended periods and to differentiate into cell types from all three germ layers both in vitro and in vivo. These characteristics of self-renewal and pluripotency enable hES cells having the potential to provide an unlimited supply of different cell types for tissue replacement, drug screening, and functional genomics studies. The hES-T3 cells with normal female karyotype cultured on either mouse embryonic fibroblasts (MEF) in hES medium (containing 4 ng/ml bFGF) (T3MF) or feeder-free Matrigel in MEF-conditioned medium (supplemented with additional 4 ng/ml bFGF) (T3CM) were found to express very similar profiles of mRNAs and microRNAs, indicating that the unlimited self-renewal and pluripotency of hES cells can be maintained by continuing culture on these two conditions. more...

(Submitter supplied) We aimed to determine whether overexpression of endoderm-specific miRNA may affect hESC differentiation. To this end, we analyzed the effect of lentiviral-based overexpression of liver-specific miR-122 on hESC differentiation, using genomewide gene microarrays. Stable overexpression of endoderm-specific miR-122 in hESC resulted in increased expression of a few endodermal markers in spontaneously-differentiating hESC, but had no clear effect on directing differentiation towards an endodermal fate; rather, it delayed the general differentiation of hESC. more...

(Submitter supplied) To assess changes in the miRNA-ome during the early stages of endothelial differentiation, the expression of mature human miRNAs at days 2, 4 and 10 of endothelial differentiation (vs pluripotent time-matched samples) in SA461 hESC cell line was analysed in a two-channel microarray. Expression of the pluripotency-associated miRNAs miR-302a – d and miR-372 and miR-373 was significantly suppressed with progression of differentiation. more...

(Submitter supplied) We used massively parallel pyrosequencing to discover and characterize microRNAs (miRNAs) expressed in human embryonic stem cells (hESCs). Sequencing of small RNA cDNA libraries derived from undifferentiated hESC and from isogenic differentiating cultures yielded a total of 425,505 high-quality sequence reads. A custom data analysis pipeline delineated expression profiles for 191 previously annotated miRNAs, 36 novel miRNAs highly conserved across vertebrates, and 291 novel candidate miRNAs. more...

(Submitter supplied) miRNA plays a critical role in a wide variety of biological processes Profiling miRNA expression during the differentiation of embryonic stem cells will help us to understand the regulation pathway of differentiation, therefore to explain disease mechanisms and to find possible therapeutical targets. In this study miRNA expressions were profiled during cardiomyocyte-specific differentiation of murine embryonic stem cells with high-throughput microarray platforms. more...

(Submitter supplied) Pluripotent hESCs can differentiate into the three primary embryonic lineages (endoderm, mesoderm, ectoderm) as well as extraembryonic tissues. Definitive endoderm (DE) is the first step into the pathway to endoderm dreived tissues (pancreas, liver, gut, lung). We used microarrays to detail the changes in microRNA expression during the transition from pluripotent hESCs into definitive endoderm.

(Submitter supplied) Type 1 diabetes is an autoimmune destruction of pancreatic islet beta cell disease, and it is important to find new alternative source of the islet beta cells to replace the damaged cells. Human embryonic stem (hES) cells possess unlimited self-renewal and pluripotency and thus have the potential to provide an unlimited supply of different cell types for tissue replacement. The hES-T3 cells with normal female karyotype were first differentiated into embryoid bodies and then induced to generate the pancreatic islet-like cell clusters, which expressed pancreatic islet cell-specific markers of insulin, glucagon and somatostatin. more...
