(Submitter supplied) Rpl22l1 is a highly conserved ribosomal protein paralog that plays a regulatory role in certain hematopoietic cell lineages. Rpl22l1-deficiency arrests the development of T cells at the DN3 stage. RNA-seq analysis was performed to identify the molecular basis for the arrest

(Submitter supplied) Human T lymphogenesis includes emergence, migration and thymus-seeding of T lymphoid precursor, followed by T-lymphocytes commitment in thymus, which are largely unknown. Here, we perform single-cell RNA sequencing using cells isolated from human hemogenic/hematopoietic sites such as aorto-gonad-mesonephros (AGM), liver, and thymic primordia spanning embryonic and fetal stages. The transcriptional atlas of thymic primordia illustrates the cellular trajectory of early T-lymphocyte development. more...

(Submitter supplied) Hi-C was used to examine long range chromatin interactions in B cell progenitors in the presence and absence of the Erg transcription factor. Specifically, OP9 cultured B220+ B-cell progenitors derived from the bone marrow of Rag1CreT/+;ErgΔ/Δ mice and from Rag1CreT/+ and Rag1Cre+/+;Erg fl/fl control mice were isolated and DNA interactions were profiled by in situ Hi-C.

(Submitter supplied) Stem cell differentiation and lineage specification depend on coordinated programs of gene expression, but our knowledge of the chromatin modifying factors regulating these events remains incomplete. Ubiquitination of histone H2A (H2A-K119u) is a common chromatin modification associated with gene silencing, and controlled by the ubiquitin-ligase polycomb repressor complex 1 (PRC1) and H2A-deubiquitinating enzymes (H2A-DUBs). more...

(Submitter supplied) MYSM1 is a transcriptional regulator essential for HSC function and hematopoiesis. We established that p53 activation is a common mechanism mediating HSC dysfunction, MPP depletion, and lymphopenia in Mysm1-deficiency, however, the specific p53-induced effectors that trigger dysfunction in Mysm1-deficient HSPCs remain unknown. Here, we performed RNA-Seq of Lin-cKit+Sca1+CD150+ and CD150- HSPCs from Mysm1-/-Puma-/-, Mysm1-/-Puma+/-, Puma-/-, and wild-type mice; (Mysm1-/-Puma+/- phenocopies Mysm1-/-). more...

(Submitter supplied) The transcription factor PU.1 is a central regulator of hematopoiesis, required for the normal differentiation of the myeloid and lymphoid lineages. Due to its essential role in early development and the importance of PU.1 in regulating several defining markers of lymphoid progenitors, its precise function in early lymphopoiesis has remained unclear. Using conditional mutagenesis and alternative lineage identification strategies, we demonstrate the developmental stage restricted function for PU.1 in early lymphopoiesis. more...

(Submitter supplied) The role of ribosome biogenesis in erythroid development is supported by the recognition of erythroid defects in ribosomopathies in both Diamond-Blackfan anemia and 5q- syndrome. Whether ribosome biogenesis exerts a regulatory function on normal erythroid development is still unknown. In the present study, a detailed characterization of ribosome biogenesis dynamics during human and murine erythropoiesis shows that ribosome biogenesis is abruptly interrupted by the drop of rDNA transcription and the collapse of ribosomal protein neo-synthesis. more...

(Submitter supplied) In order to identify genes that are activated in differentiating WT ESCs, but are missing in Tal-1-/- and Runx1-/- ESCs, and which might be involved in the generation of definitive hematopoietic progenitors and their specification thereafter, we performed microarray analyses on purified Flk-1+ cells, differentiated from these ESCs for 4, 5, and 6 days “in vitro”.

(Submitter supplied) Zinc finger protein 521 (ZFP521), a DNA-binding protein containing 30 Krüppel-like zinc fingers, has been implicated in the differentiation of multiple cell types, including hematopoietic stem and progenitor cells (HSPC) and B lymphocytes. Here, we report a novel role for ZFP521 in regulating the earliest stages of hematopoiesis and lymphoid cell development through soluble microenvironmental proteins. more...
