Single-cell RNA-seq reveals neural progenitor subpopulations and divergent astrocyte lineages

Project description:Astrocytes are one of the most abundant cell types in the mammalian central nervous system. Their diversity was widely investigated in the adult brain recently. However, the heterogeneity of astrocyte progenitors in their early developmental stage is still not clear. In this study, we dissected the subpopulations of neural progenitor cells at the neurogenesis and the early gliogenesis stages by single-cell RNA sequencing analysis. Interestingly, we identified two astrocyte progenitor subgroups from the cerebral cortex. The astrocyte subgroups highly express Sparc or Sparcl1, which were reported have contrary functions in astrocytes to regulate synapse formation. Further analysis for subpopulations of neural progenitors from the ventral forebrain also identified two astrocyte progenitor subgroups, showing similar gene expression patterns as in the cortex. Surprisingly, clustering analysis between the subpopulations from the dorsal and the ventral forebrains showed that the astrocyte progenitors expressing Sparc or Sparcl1 were clustered together, irrespective of their derived regions. These results showed an early divergence of astrocyte progenitors and their cross-regional conservation at the start of gliogenesis during brain development.

Proteome in human hematopoietic stem and progenitor cell subpopulations from polycythemia vera patients and controls

Project description:Polycythemia vera (PV) is a myeloproliferative neoplasm (MPN) characterized by hyper-proliferation of the erythroid, megakaryocytic and granulocytic lineages and the presence of an activating mutation in JAK2. To elucidate mechanisms that regulate PV stem cells, we applied a newly developed data-independent acquisition (DIA) mass spectrometry (MS) technology to purified hematopoietic stem and progenitor cell (HSPC) subpopulations of patients with chronic and progressed PV. Proteomic analyses were supplemented by RNA-sequencing (RNA-seq) and identified targets validated by flow cytometry and functional in vitro assays.

A Molecular Switch for Neuroprotective Astrocyte Reactivity

Project description:Astrocytes differentiate into a spectrum of neurotoxic and neuroprotective reactive subpopulations after CNS injury and in disease. In astrocyte conditional ADCY10 (sAC) knockout mice, reactive astrocytes exhibit a shift towards neurotoxic phenotypes implicating sAC as a critical regulator of neuroprotective astrocyte differentiation.

Divergent transcriptional regulation of astrocyte reactivity across disorders [TR_ATAC_SCI]

Project description:Single-nuclei Assay for Transposase-Accessible Chromatin with sequencing (snATACseq) was applied to examine chromatin landscape changes and transcriptional regulator (TR) DNA motif accessibility in reactive astrocytes following traumatic spinal cord injury (SCI). Astrocyte nuclei were isolated from the spinal cord of wild type mice and mice with astrocyte-specific conditional gene deletion (cKO) of test-case TRs, SMARCA4 (Smarca4-astro-cKO) or STAT3 knockout (Stat3-astro-cKO). Comparison of differential chromatin accessibility revealed substantial remodeling during astrocyte reactivity, with more chromatin opening than closing. Marked alterations in access to SCI reactivity-associated TR motifs were also detected.

Divergent transcriptional regulation of astrocyte reactivity across disorders [TR_ATAC_LPS]

Project description:Single-nuclei Assay for Transposase-Accessible Chromatin with sequencing (snATACseq) was applied to examine chromatin landscape changes and transcriptional regulator (TR) DNA motif accessibility in reactive astrocytes following neuroinflammatory insult by systemic administration of lipopolysaccharide (LPS). Astrocyte nuclei were isolated from the spinal cord of wild type mice and mice with astrocyte-specific conditional gene deletion (cKO) of test-case TRs, SMARCA4 (Smarca4-astro-cKO) or STAT3 knockout (Stat3-astro-cKO). Comparison of differential chromatin accessibility revealed substantial remodeling during astrocyte reactivity, with more chromatin opening than closing. Marked alterations in access to LPS reactivity-associated TR motifs were also detected.

RNA-seq in different hematopoietic stem and progenitor cell subpopulations of patients with chronic and progressed polycythemia vera and controls

Project description:Hematopoietic stem/multipotent progenitor cells (HSC/MPPs, referred to as HSCs) can differentiate into functionally divergent cell lineages including common myeloid progenitors (CMPs), megakaryocyte-erythrocyte progenitors (MEPs) or granulocyte-macrophage progenitors (GMPs). When this stem cell differentiation process is altered, abnormal (pre)leukemic stem cell subpopulations may form, eventually resulting in clonal hematopoiesis and in the onset of chronic or acute leukemias such as for example polycythemia vera (PV) or acute myeloid leukemia (AML). To understand the molecular and biochemical changes underlying trilineage hyperproliferation in PV and the process of progression to post-PV myelofibroses (post-PV MF) or post-PV acute myeloid leukemia (post-PV AML), highly refined analyses of PV stem and progenitor cells are required. We performed transcriptomics and proteomics analyses in hematopoietic stem and progenitor cells of patients with chronic and progressed PV as well as controls to identify key molecular changes in these cell subpopulations for disease manifestation and progression.
