Project description:Mesenchymal stem/stromal cells (MSCs) are multipotent cells that can differentiate into a variety of cell types forming connective tissue and skeleton, and are essential participants in the development of all organs. However, MSC precursors remain largely unknown. In human embryonic stem cells (hESCs) directed to mesendodermal differentiation through coculture with OP9 stromal cells, we identified a population of mesodermal cells by surface expression of apelin receptor (APLNR1). APLNR+ cells were enriched with precursors generating compact spheroid colonies in semisolid suspension culture. Being formed by single cells, these colonies consisted of a uniform population of mesenchymal cells with a transcriptional profile representative of embryonic mesenchyme originating from lateral plate/extraembryonic mesoderm. Mesenchymal colony formation required serum-free medium and FGF2 as a colony-forming factor, could be significantly enhanced by PDGF-BB, but suppressed by VEGF. When transferred to the adherent cultures in serum-free medium with FGF2, individual colonies gave rise to multipotential mesenchymal cell lines with typical phenotype (CD146+CD105+CD73+CD31-CD43-CD45-), differentiation (chondro-, osteo-, and adipogenesis) and proliferation (>80 doublings) potentials. Consistent with lineage-restricted differentiation pattern, neither endothelial nor hematopoietic cells could be produced from adherent mesenchymal cultures, however endothelial cells could be derived from mesenchymal colonies in the early days of colony-forming culture suggesting that mesenchymal cells arose from cells with primary angiogenic potential (mesangioblasts). Together these studies identified mesangioblasts as the earliest clonogenic mesenchymal precursors at this stage of their specification from mesoderm. This set (11 samples) of expression data is sequential stages of MSC development from hESCs (H1), namely ALPNR+ mesodermal precursors isolated on day 2 and day 3 differentiation, mesangioblast (MB) cores (Day 2 H1-derived cores), hemangioblast (HB) cores (day 3 H1-derived cores), mesangioblast (MB) and hemangioblast (HB) colonies, and colony-derived MSC lines at passage 1 and 5.

Project description:Analysis of genes enriched in MIXL1+ sorted cells during primitive streak induction identified Apelin receptor (APLNR), a highly conserved member of the G-protein coupled receptor family. Depending upon the growth factor conditions used for differentiation, APLNR+ cells identified both posterior mesodermal and anterior mesendodermal components of the primitive streak. APLNR+ cells isolated from mesodermal differentiated cultures were enriched in hematopoietic blast colony forming cells (Bl-CFCs) and the addition of Apelin peptide enhanced the frequency and growth of both hematopoietic colonies and hESC-derived endothelial cells. These studies identified APLNR as a marker of primitive streak-like cells differentiated from hESCs and defined a novel role for Apelin as a regulator of early human hematopoiesis.

Project description:Genome wide DNA methylation profiling of hESC-derived mesothelium (MesoT), hESCs and hESC-derived splanchnic mesoderm (SplM) compared to primary human tissue samples. The Illumina Infinium HumanMethylation450 BeadChip kit was used to obtain DNA methylation profiles across approximately 450,000 methylation sites. Samples include 2 WA09 hESCs, 2 hESC-derived splanchnic mesoderm and 3 hESC-derived mesothelium replicates.

Project description:Purpose: The goals of this study are to identify key transcription factors governing differentiation through comparing thel transcriptome profilings in hESC samples collected from day 0 to day 4 after hematopoietic differentiation. Conclusions: 68 transcriptional factors were found up-regulated gradually and steadily during early hematopoietic differentiation of H1 hESCs. After 4 days of differentiation, the mRNA levels of all these factors increased by more than 10 folds.

Project description:The realization of human embryonic stem cells (hESC) as a model for human developmental hematopoiesis and potential cell replacement strategies relies on an improved understanding of the extrinsic and intrinsic factors regulating hematopoietic-specific hESC differentiation. Mesenchymal stem cells (hMSCs) are multipotent cells of mesodermal origin that form part of hematopoietic stem cell niches and have an important role in the regulation of hematopoiesis through production of secreted factors and/or cell-to-cell interactions. We have previously shown that hESCs may be successfully maintained feeder-free using hMSC-conditioned media (MSC-CM). Here, we hypothesized that hESCs maintained in MSC-CM may be more prone to differentiation towards hematopoietic lineage than hESCs grown in standard human foreskin fibroblast (HFF)-conditioned media (HFF-CM). We report that specification into hemogenic progenitors and subsequent hematopoietic differentiation and clonogenic progenitor capacity is robustly enhanced in hESC lines maintained in MSC-CM. Interestingly, co-culture of hESCs on hMSCs fully abrogates hematopoietic specification of hESCs suggesting that the improved hematopoietic differentiation is mediated by MSC-secreted factors rather than by MSC-hESC physical interactions. To investigate the molecular mechanism involved in this process, we analyzed global (LINE-1) methylation and genome-wide promoter DNA methylation. Human ESCs grown in MSC-CM showed a decrease of 20% in global DNA methylation and a promoter DNA methylation signature consisting in 45 genes commonly hypomethylated and 102 genes frequently hypermethylated. Our data indicate that maintenance of hESCs in MSC-CM robustly augments hematopoietic specification and that the process seems mediated by MSC-secreted factors conferring a DNA methylation signature to undifferentiated hESCs which may influence further predisposition towards hematopoietic specification.
