(Submitter supplied) Aging of hematopoietic stem cells (HSCs) leads to several functional changes, including alterations affecting self-renewal and differentiation. While it is well established that many of the age-induced changes are intrinsic to HSCs, less is known about the stability of this state. Here, we entertained the hypothesis that HSC aging is driven by the acquisition of permanent genetic mutations. To examine this issue at a functional level in vivo, we applied induced pluripotent stem (iPS) cell reprogramming of aged hematopoietic progenitors and allowed the resulting aged-derived iPS cells to reform hematopoiesis via blastocyst complementation. more...

(Submitter supplied) Somatic stem cells mediate tissue maintenance for the lifetime of an organism. Despite the well-established longevity that is a prerequisite for such function, accumulating data argue for compromised stem cell function with age. Identifying the mechanisms underlying age-dependent stem cell dysfunction is therefore key to understand the aging process. Using a model that carries a proofreading defective mitochondrial DNA polymerase, we demonstrate hematopoietic defects reminiscent of premature HSC aging including anemia, lymphopenia and myeloid lineage skewing. more...

Analysis of hematopoietic stem cells (HSCs) from mid-aged mutator females that express a proofreading-defective form of the mitochondrial DNA polymerase gamma (POLG). Results provide insight into the molecular mechanisms underlying multiple aspects of aging accelerated in the mutator model.

(Submitter supplied) Developmental pathways that orchestrate the fleeting transition of endothelial cells into haematopoietic stem cells remain undefined. Here we demonstrate a tractable approach for fully reprogramming adult mouse endothelial cells to haematopoietic stem cells (rEC-HSCs) through transient expression of the transcription-factor-encoding genes Fosb, Gfi1, Runx1, and Spi1 (collectively denoted hereafter as FGRS) and vascular-niche-derived angiocrine factors. more...

(Submitter supplied) Here, we use single-cell RNA-Seq to examine variation between individual hematopoietic stem and progenitor cells from two mouse strains (C57BL/6 and DBA/2) as they age. We prepared libraries from long-term (LT-HSCs) (LSK CD150+CD48-), short-term hematopoietic stem cells (ST-HSCs) (LSK CD150-CD48-) and multipotent progenitors (MPPs) (LSK CD150+CD48+) from young (2-3 months) and old mice (22 months for C57BL/6 and 20 months for DBA/2). more...

(Submitter supplied) Full pluripotency of induced pluripotent stem (iPS) cells has been determined as viable all-iPS mice can be generated through tetraploid complementation. Subsequently, activation of imprinted Dlk-Dio3 gene cluster has been suggested to correlate with the pluripotency of iPS cells1. However, evidence from recent studies has demonstrated that loss of imprinting at the Dlk-Dio3 locus did not correlate strictly with the reduced pluripotency of iPS cells. more...

(Submitter supplied) The infant leukemia-associated gene, Ott1 (Rbm15), has broad regulatory effects on embryonic development and hematopoiesis. Embryonic deletion of Ott1 results in defects to the placenta, spleen and heart. Conditional deletion within the adult hematopoietic compartment demonstrates a requirement in pre-B development and inhibitory roles in myeloid progenitor and megakaryocyte populations. Ott1-deleted bone marrow has an expansion of the Lin- Sca-1+ c-Kit+ (LSK) population which includes the hematopoietic stem cell (HSC) population. more...
