(Submitter supplied) To ensure the rapid response to stimuli, some HSCs are specifically prepared (primed) for tasks involving activation and reconstitution. However, the key factors that regulate the primed state of HSCs are largely unknown. Here we report that Med23 controls the formation of myeloid-primed HSCs. Ablation of Med23 in hematopoietic system leads to lymphocytopenia. Moreover, Med23-deficient HSCs undergo myeloid-biased differentiation and lose the self-renewal capacity. more...

(Submitter supplied) In response to myeloablative stresses, HSCs are rapidly activated to replenish myeloid progenitors, while maintaining full potential of self-renewal to ensure life-long hematopoiesis. However, the key factors that orchestrate HSC activities during physiological stresses remain largely unknown. Here we report that Med23 controls the myeloid potential of activated HSCs. Ablation of Med23 in hematopoietic system leads to lymphocytopenia. more...

(Submitter supplied) The Hematopoietically-expressed homeobox transcription factor (Hhex) is important for the maturation of definitive hematopoietic progenitors and B-cells during development. We have recently shown that in adult hematopoiesis, Hhex is dispensable for maintenance of hematopoietic stem cells (HSCs) and myeloid lineages but essential for the commitment of Common Lymphoid Progenitors (CLPs) to lymphoid lineages. more...

(Submitter supplied) The hematopoietic stem cell (HSC) compartment is heterogeneous, yet our understanding of the identities of different HSC subtypes is limited. Here we show that platelet integrin CD41 (αIIb), currently thought to only transiently mark fetal HSCs, is expressed on an adult HSC subtype that accumulates with age. CD41+ HSCs were largely quiescent and exhibited myeloerythroid and megakaryocyte gene priming, governed by Gata1, whereas CD41- HSCs were more proliferative and exhibited lymphoid gene priming. more...

(Submitter supplied) To investigate the molecular mechanism of Uhrf1 in controlling the self-renewal versus differentiation of FL-HSCs, high-throughput sequencing was performed to analyze the transcriptomes of WT and Uhrf1-deficient FL-HSCs.Consistent with the erythroid-biased differentiation of Uhrf1-deficient FL-HSCs, genes involved in erythrocyte differentiation were significantly enriched in Uhrf1-deficient FL-HSCs according to the Gene Ontology (GO) enrichment analysis. more...

(Submitter supplied) Previous studies have illustrated the importance of Jak1-mediated cytokine signaling in immunological and neoplastic diseases such that JAK1 inhibition is currently being investigated in clinical trials. However, the role of Jak1 in hematopoietic stem cell (HSC) function has not been delineated. Here we show that conditional Jak1 loss in hematopoietic cells reduces HSCs and markedly alters lymphoid/myeloid differentiation in vivo. more...

(Submitter supplied) In this study, we have used inducible and tissue-specific genetic deletion to investigate the function of HBO1 in the hematopoietic system. RNA-seq was used to examine the dependence of gene expression on the presence of HBO1(KAT7). Two different conditional expression sytems were used to induce Cre recombinase and delete a floxed allele of HBO1 in this study. This was to control for the treatement effect during Cre induction (interferon induction of Mx1-cre vs. more...

(Submitter supplied) KAT7 (HBO1) is a histone acetyltransferase required for histone H3 lysine 14 acetylation (H3K14ac) and normal levels of gene expression in hematopoietic stem and progenitor cells (HSPCs). The loss of H3K14ac was detected by western blot in whole bone marrow and by flow cytometry in specific HSPC populations. In order to determine the normal distribution of H3K14ac in the HSPC population a CUT&Tag experiment was performed using lineage negative, cKit positive Sca1 positive cells (LSK) and lineage negative, cKit positive Sca1 negative cells (progenitor cells). more...

(Submitter supplied) Hematopoietic stem cell (HSC) transplantation has the potential to cure blood disorders but is limited by donor availability. Hence innovative approaches to engineer HSC are critically needed. HoxB4 over-expression in mouse embryonic stem cell-derived HSC (ESC-HSC) confers long-term engraftment, yet lacks efficient lymphogenesis. Transcriptome comparison of ESC-HSC versus embryo-derived HSC showed that ESC-HSC are deficient in expression programs activated by Notch. more...

(Submitter supplied) Hematopoietic stem cells (HSCs) and lymphoid-primed multi-potential progenitors (LMPPs) are able to initiate both lymphoid and myeloid differentiation. We show here that the transcriptional repressor Gfi1 (growth factor independence 1) implements a specific gene expression program in HSCs and LMPPs that is critical for their survival and lymphoid differentiation potential. We present evidence that Gfi1 is required to maintain expression of genes involved in lymphoid development such as Flt-3, IL7R, Ebf1, Rag1, CCR9 and Notch1 and controls myeloid lineage commitment by regulating expression of genes such as Hoxa9 or M-CSFR. more...

Analysis of Lin-Sca1+ckit+Flt3- (LSKFlt3-) hematopoietic stem cells (HSC) depleted of growth factor independence 1 (Gfi1). Transcriptional repressor Gfi1 restricts HSC proliferation and is essential to self-renewal. Results provide insight into molecular mechanisms underlying Gfi1 effects in HSCs.

(Submitter supplied) We sequenced mRNA from 12 single newborn mouse calvaria tissues ( from 3 control and 3 Med23-/- cKO mice from a litter; 3 wildtype and 3 Runx2+/- mice from another litter) to investigate the correlation between Med23 and Runx2 in terms of affect on the mRNA level by their deficiencies. We find there is a positiove correlation in gobal gene expression affected by defiencies of the two genes.

(Submitter supplied) Plant homeodomain finger gene 6 (PHF6) encodes a 365-amino-acid protein containing two plant homology domain fingers. Germline mutations of human PHF6 cause Börjeson–Forssman–Lehmann syndrome, a congenital neurodevelopmental disorder. Loss-of-function mutations of PHF6 are detected in patients with acute leukemia, mainly of T cell lineage and in a small proportion of myeloid lineage. The functions of PHF6 in physiological hematopoiesis and leukemogenesis remain incompletely defined. more...

(Submitter supplied) Hematopoiesis is a series of lineage differentiation programs initiated from hematopoietic stem cells (HSCs) in the bone marrow (BM). To maintain lifelong hematopoiesis, the pool of HSCs is precisely maintained by diverse molecular mechanisms. CCCTC-binding factor (CTCF) is a DNA-binding zinc-finger protein which regulates its target gene expression by organizing higher order chromatin structures. Currently, the role for CTCF in controlling HSC homeostasis is unknown. more...
