Project description:G1ME cells are GATA1-deficient murine bipotential megakaryocyte/erythrocyte progenitor cells derived from Gata1-negative murine ES cells. In order to assess the impact of GATA1 on gene regulation and cell differentiation, an expression construct was used to transiently produce high levels of GATA1. Cells transduced with this construct or a vector control were harvested at 18 and 42 hours, and gene expression was analyzed using Affymetrix MOE430 version 2 arrays.

Cells transduced with this construct or a vector control were harvested at 18 and 42 hours, and gene expression was analyzed using Affymetrix MOE430 version 2 arrays. Both vector control and GATA1-expressing cells were isolated by FACS for GFP and 18 and 42 hours. Biologic triplicates were performed for each construct at each timepoint.

Project description:The transcriptional activiy of GATA1s was compared to GATA1 through gene expression analysis in a cell line model with both erythroid and megakaryocyte differentiation. G1ME cells were derived from Gata1- mouse ES cells and have both megakaryocyte and erythrocyte differentiation potential upon reconstitution of GATA-1 expression (Stachura 2006). HA-tagged full length or short GATA-1 were expressed in G1ME cells grown in TPO via retroviral transductions. The cells were sorted for GFP positivity 68 hours post-transduction and then were allowed to recover in normal growth medium for 4h. Total RNA was then isolated using RNeasy kit from Qiagen 72 hours post-transduction.

Project description:Platelets are produced by megakaryocytes, deriving from megakaryocyte erythrocyte progenitors (MEP) in the bone marrow. Increased megakaryocyte expansion across common autoimmune diseases was shown for rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and primary Sjögren’s syndrome (pSS). In this context, we evaluated the role of the microbial-derived short chain fatty acid (SCFA) propionate on megakayriocytes in vitro. Using RNA sequencing we characterized the consequences of propionate exposure on the megakaryoblast cell line Meg-01.

Project description:Dhh negatively regulates multiple stages of erythrocyte differentiation. In Dhh-deficient bone marrow, the common myeloid progenitor (CMP) population was increased, but differentiation from CMP to granulocyte/macrophage progenitor was decreased, and the mature granulocyte population was decreased, compared with wild-type (WT). In contrast, differentiation from CMP to megakaryocyte/erythrocyte progenitor was increased, and the megakaryocyte/erythrocyte progenitor population was increased. In Dhh-deficient spleen and bone marrow, BFU-Es and erythroblast populations were increased compared with WT. During recovery of hematopoiesis after irradiation, and under conditions of stress-induced erythropoiesis, erythrocyte differentiation was accelerated in both spleen and bone marrow of Dhh-deficient mice compared with WT. To investigate possible mechanisms for its regulation of erythropoiesis we carried out RNAsequencing on Facs-sorted erythroblast population II (CD71+Ter119+) cells from Dhh-/-, Dhh+/- and WR mice.

Project description:We leverage the extraordinary molecular diversity of modified heparan sulfate (HS) glycans 8 to establish cellular glycotypes, defined by binding patterns of a panel of flow-cytometry compatible single-chain variable fragment antibodies (scFvs) specific for differentially modified HS. We find distinct glycotypes between closely related hematopoietic progenitors and lineages. The glycotypes of murine and human hematopoietic stem and progenitor cells (HSPCs) reveal dynamic yet similar HS modification patterns in vivo and in vitro, including along megakaryocyte and erythrocyte differentiation. Prospective HS scFv-based sorting identifies new cellular subtypes from both immunophenotypic megakaryocyte-erythrocyte progenitors and heterogeneous pools of HSPCs, thus offering additional discriminative power beyond conventional CD markers. Mechanistically, single-cell RNAseq revealed that a heptad of HS-related genes participate in megakaryocyte-erythrocyte fate determination and are reflective of the HS epitope recognized by specific HS scFvs. In summary, HS glycotyping establishes a role for HS modification patterns in hematopoietic lineage differentiation in mouse and human, and provides an orthogonal approach to define and isolate viable cell types across different cell lineages and species at unprecedented resolution.
