Transcriptome of Primitive Human Hematopoietic Cells: A New Resource to Find hHSC-Specific Genes

ABSTRACT: We analysed the transcriptome of different HSC-enriched subpopulations of cells sorted from human umbilical cord blood and isolated from several individuals with different genetic backgrounds. We aim at identifying new cell surface markers associated with human HSC and downstream mature hematopoietic cell activity.

RNA-seq of uncultured CD112high and CD112low and cultured long-term (LT) and short-term (ST) human hematopoietic stem cells (HSC) overexpressing INKA-1

Project description:RNA-seq of uncultured CD112high and CD112low long-term(LT) human hematopoietic stem cells (HSC) and cultured and lentiviral transduced (CTRL, INKA1-OE) LT- and short-term HSC from umbilical cord blood We performed RNA-sequencing to elucidate the biological pathways (1) altered by INKA1 overexpression in LT-HSC and ST-HSC that may contribute to the induced transient restraint in generating proliferative hematopoietic output in vivo and in vitro; and (2) that underlie the differential in vitro priming and regeneration phenotypes of CD112high and CD112low LT-HSC. Therefore, we prospectively isolated indicated subpopulations from 3 independent human umbilical cord blood pools and subjected them either to RNA-sequencing directly or following culture, lentiviral transduction and purification of the transduced cell fractions. We show that distinct subsets of human LT-HSC respond differently to regeneration-mediated stress and that INKA1 governs these distinct stemness states where CD112low LT-HSC are marked by an alternative state of quiescence with high INKA1 preserving self-renewal and regenerative capacity upon successive rounds of regeneration-mediated stress.

ATAC-seq of uncultured CD112high and CD112low long-term(LT) human hematopoietic stem cells (HSC) from umbilical cord blood

Project description:We performed ATAC-sequencing to elucidate the chromatin accessibility that underlie the differential in vitro priming and regeneration phenotypes of CD112high and CD112low LT-HSC. Therefore, we prospectively isolated these subpopulations from 3 independent human umbilical cord blood pools and subjected to ATAC-sequencing directly. We show that distinct subsets of human LT-HSC respond differently to regeneration-mediated stress and that INKA1 governs these distinct stemness states where CD112low LT-HSC are marked by an alternative state of quiescence with high INKA1 and low H4K16ac preserving self-renewal and regenerative capacity upon successive rounds of regeneration-mediated stress.

Transcriptomic profiling of 27-year cryopreserved umbilical cord blood HSCs/HPCs

Project description:Umbilical cord blood banking is critical for the success of umbilical cord blood transplants. Here we analyzed transcriptomic differences between 27-year cryopreserved umbilical cord blood hematopoietic stem cells (HSCs) and multipotent progenitor cells (MPPs) and those derived from fresh cord blood. We also leveraged differences in engraftment capacity to examine the transcriptomes of HSCs/HPCs defined by engraftment capacity, demonstrating the feasibility of this approach for identifying potency markers to aid in the selection of cord blood units for transplantation and revealing novel potential regulators of cord blood HSC/HPC engraftment.

Transcription profiling of human umbilical cord blood and adult bone marrow CD34+CD33-CD38-Rho(lo)c-kit+ cells to identify candidate regulators of HSC self-renewal versus differentiation fate decisions

Project description:The global gene expression profiles of human umbilical cord blood and adult bone marrow CD34+CD33-CD38-Rho(lo)c-kit+ cells, enriched for hematopoietic stem/progenitor cells (HSC) with CD34+CD33-CD38-Rho(hi) cells, enriched in committed hematopoietic progenitor cells (HPC), were compared to identify candidate regulators of HSC self-renewal versus differentiation fate decisions.

Proteomic analysis of exosomes isolated from human umbilical cord serum by mass spectrometry and preliminary study of their biological activities in cultured hepatocellular carcinoma cell lines

Project description:Exosomes are membranous extracellular vesicles 50–100 nm in size and are involved in cellular communication via the delivery of proteins, lipids, and RNAs. Emerging evidence shows that exosomes play a critical role in cancer. A recent study has revealed that maternal and umbilical cord serum-derived exosomes may enhance endothelial cell proliferation and migration. However, the role of exosomes isolated from the human umbilical cord in cancer development has not been investigated. To explore the potential differences in the composition and function of proteins from umbilical cord blood exosomes and maternal serum exosomes, we conducted a proteomic analysis of exosomes by mass spectrometry and bioinformatics analysis. We used the CCK-8 assay and flow cytometry to study the biological effects of umbilical serum exosomes on hepatoma cells. Our study shows that umbilical cord blood is enriched with proteins involved in ECM-receptor interactions, which may be closely related to cell metastasis and proliferation. Our findings indicate that exosomes derived from human umbilical serum can suppress the viability of hepatoma cells and may induce apoptosis of hepatoma cells. This evidence suggests that umbilical cord serum-derived exosomes may be potential leads for the development of biotherapy for liver cancer.

Prostaglandin dose response on hematopoietic stem cells (25 & 37 deg C)

Project description:Umbilical cord blood (UCB) is a valuable source of hematopoietic stem cells (HSCs) for use in allogeneic transplantation. Key advantages of UCB are rapid availability and less stringent requirements for HLA matching. However, UCB contains an inherently limited HSC count, which is associated with delayed time to engraftment, high graft failure rates and early mortality. 16,16 dimethyl prostaglandin E2 (dmPGE2) was previously identified to be a critical regulator of HSC homeostasis and we hypothesized that a brief ex vivo modulation could improve patient outcomes by increasing the "effective dose" of HSCs. Molecular profiling with Affymetrix GeneChips were used to evaluate if increasing the concentration of prostaglandin at 25 and 37 deg C could increase biological responses. Isolated human CD34+ cells from umbilical cord blood were incubated ex vivo in Stem Span (SS) media evaluating five concentrations of 16,16-dmPGE2 (0.1uM, 1uM, 10uM, 50uM, and 100uM) or Vehicle (DMSO) for 2 hours at 25 or 37 deg C. Total RNA was isolated post incubation and analyzed on Affymetrix microarrays for pathway activation.
