T cell regeneration from pluripotent stem cells by defined transcription factors Runx1 and Hoxa9 [single hematopoietic cells (iR9-iHEC&iR9-iHPC) II]

ABSTRACT: We identified that the coordinated expression of exogenous Runx1 and Hoxa9 during the haematopoietic induction process from mouse PSC resulted in a type of induced hemogenic endothelial cells (iHEC). The single iHEC can be robustly educated into induced haematopoietic progenitor cells (iHPC), which gave rise to induced T cells (iT cells) with abundant TCRαβ repertoire in vivo. We sorted the single iHEC and iHPC from day-14, day-17, day-21 cell products derived from 241 iR9-ES and performed single-cell RNA-Seq.

De novo generation of macrophage from placenta-derived hemogenic endothelium

Project description:We profile the transcriptional landscape of mouse fetal placenta and identify four distinct types of haematopoietic stem/progenitor cells (HSPCs) during mid-gestation using single-cell RNA sequencing. We experimentally validate and uncover that a subpopulation of placental endothelial cells exhibits hemogenic endothelial (HE) potential and shares transcriptional features with HE cells in the aorta-gonad-mesonephros (AGM) region.

Regeneration of immunocompetent B lymphopoiesis from pluripotent stem cells guided by transcription factors

Project description:We identified that the coordinated expression of exogenous transcription factors(Lhx2, Hoxa9, and Runx1), efficiently guides PSC-derived hematopoietic progenitors (iHPC) preferentially towards B cell lineage commitment, which successfully regenerate B lymphopoiesis in B-cell deficient animals. Of note, the abundancy of in vivo lymphopoiesis includes pro/pre-B progenitors, immature B cells, and all subsets of mature B1a, B1b, FO B and MZ B reconstitution in vivo. We performed single-cell RNA-Seq using the sorted GFP+CD45+ Lin- cells from the bone marrow of recipients at day 7.5 after iHPC transplantation.

Identification and characterization of regenerative innate lymphoid cells from pluripotent stem cells [R9_DAY7.5_10X_genomics]

Project description:We identified that synergistic and inducible expression of Runx1 and Hoxa9 in pluripotent stem cells gave rise to engraftable iHPC capable of developing into mature ILCs in the Rag2-/-Il2rg-/- recipients. The regenerative ILCs were detected in multiple tissues including intestine, lung, liver, spleen and thymus. We performed single cell RNA-seq on the sorted GFP+CD45.2+Lin- cells from the bone marrow of recipients at day 7.5 after iHPC transplantation. Single-cell transcriptome illustrated the existence of regenerative ILC-related progenitors including iLP, iILCP, iILC1/3P and iILC2P, and the cellular trajectory of regenerative ILCs development in vivo was closely resembles the natural ILCs development.

Gene expression profile at single cell level of hESC H9 derived hemognic niches at Day 18 of in vitro differentiation

Project description:Small drug (SB/CHIR) treatment and orbital shear treatment promotes the generation of hemogenic endothelium and multipotent hematopoieitic progenitor cells. We used single cell RNA sequencing (scRNA-seq) to analyze the diversity of hemogenic niches derived from hESC H9 line at day 18 of in vitro differentiation.

Gene expression profile of HoxA9 over expressing and empty vector (EV) control Hemato-Endothelial Progenitors (HEPs) subpopulations

Project description:During hematopoietic differentiation of hESCs, HOXA9 expression parallels hematopoietic development but is restricted to the hemogenic precursors (HEP, CD31+CD34+CD45-), and diminishes as HEPs differentiate into blood cells (CD45+). Enforced expression of Hoxa9 in hESCs robustly promoted differentiation into primitive (CD34+CD45+) and total (CD45+) blood cells with higher clonogenic (CFU) potential. To identify patterns of gene expression that could explain at the molecular level the developmental impact of HOXA9 in hematopoietic commitment of hESCs, we performed gene expression profile in FACS-purified EV- and HOXA9-HEPs. 10^5 HoxA9 over expressing and EV control HEPs purified by FACS from H9 and AND1 hEBs at day 15 of hematopoietic differentiation were used for gene expression analysis using Whole Human Genome Oligo Microarray chips (Agilent Technologies).

Hemogenic Endothelium transcriptome along the timeline of hESC differentiation

Project description:The differentiation of human embryonic stem cells to hematopoietic lineages initiates with the specification of hemogenic endothelium, a transient specialized endothelial precursor of all blood cells.Unfortunately, absence of hemogenic endothelium-specific markers as well as lack of consensus in the timing of hemogenic potential analysis and methodologies used to study the hematopoietic potential of this precursor prevents reaching clear and definite conclusions. Here, we demonstrate that the hemogenic potential of the endothelium precursor population sharply decline over the course of the differentiation process. Poly(A) RNA-sequencing on CD31+CD144+ population at day 6, day 8 and day 10 of EB diffferentiation with or without the addition of cytokines. Comparasion with hematopoietic committed population CD31+CD144- from day 10 of EB differentiation.

Differential gene expression of TLR7 overexpressing inflammatory hemophagocytes, Ly6Chi Monocytes, and Red Pulp Macrophages

Project description:We have defined a novel population of monocyte-derived hemophagocytes (inflammatory hemophagocytes (iHPC)) found in situations of inflammation, such as TLR7.1 mice that overexpress TLR7. These iHPC are similar yet distinct from red pulp macrophages (RPM) and differentiate in response to chronic TLR7 signals. In vivo, iHPC phagocytose red blood cells and platelets causing anemia and thrombocytopenia. We performed this study to further understand iHPC and their relationship to RPM and monocytes and determine what gene signatures make them unique.

Pharmacological Induction of a Progenitor State for the Efficient Expansion of Primary Human Hepatocytes

Project description:Transplantation of genetically corrected hepatocytes is an attractive alternative to liver transplantation but is hampered by the low amplification potential of these cells in vitro. Here, we describe a method for generating proliferative hepatic progenitor cells (iHPC) from human hepatocytes as an expandable cell source for liver therapy. Dedifferentiation of primary hepatocytes to iHPC was achieved in less than 7 days by culturing the cells in medium with a cocktail of growth factors and small molecules. In culture, iHPC expressed a combination of endoderm hepatic progenitor and mesenchymal stem cell markers and proliferated vigorously, allowing for their expansion by at least 104 times. RNA sequencing of iHPC demonstrated that they displayed far more subtle changes in both transcriptome and transposcriptome, compared to hepatocyte-derived iPSC. Finally, transplantation of iHPC into the liver of immuno-deficient mice showed iHPC differentiation potential in vivo, without triggering detectable tumor development.
