Hematopoiesis [PDF]

open access: bronzeJournal of Allergy and Clinical Immunology, 1994
Cellular turnover of the hematopoietic system is supported by a small population of cells termed hematopoietic stem cells. Stem cells are capable of self-renewal and differentiation into individual lymphomyeloid lineages. Available evidence indicates that the decision of a stem cell to self-renew or differentiate and the decision of a multipotential ...

Causes and Consequences of Clonal Hematopoiesis.

open access: yesBlood, 2023
Clonal hematopoiesis (CH) describes the outsized contribution of expanded clones of hematopoietic stem and progenitor cells (HSPCs) to blood cell production. The prevalence of CH increases dramatically with age.

Genome-wide analyses of 200,453 individuals yield new insights into the causes and consequences of clonal hematopoiesis

open access: yesNature Genetics, 2022
Clonal hematopoiesis (CH), the clonal expansion of a blood stem cell and its progeny driven by somatic driver mutations, affects over a third of people, yet remains poorly understood.

Hematopoiesis in numbers

open access: yesTrends in Immunology, 2021
Hematopoiesis is a dynamic process in which stem and progenitor cells give rise to the ~1013 blood and immune cells distributed throughout the human body. We argue that a quantitative description of hematopoiesis can help consolidate existing data, identify knowledge gaps, and generate new hypotheses.

CD14+ monocytes repress gamma globin expression at early stages of erythropoiesis

open access: yesScientific Reports, 2021
In β-hemoglobinopathies, reactivation of gamma- at the expense of beta-globin is a prominent therapeutic option. Expression of the globin genes is not strictly intrinsically regulated during erythropoiesis, supported by the observation that fetal ...

Hematopoiesis [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2012
Enormous numbers of adult blood cells are constantly regenerated throughout life from hematopoietic stem cells through a series of progenitor stages. Accessibility, robust functional assays, well-established prospective isolation, and successful clinical application made hematopoiesis the classical mammalian stem cell system. Most of the basic concepts

Hematopoiesis [PDF]

open access: yesDevelopment, 2013
Hematopoiesis – the process by which blood cells are formed – has been studied intensely for over a century using a variety of model systems. There is conservation of the overall hematopoietic process between vertebrates, although some differences do exist.

Prediction of Risk for Myeloid Malignancy in Clonal Hematopoiesis

open access: yesBlood, 2022
BACKGROUND Clonal hematopoiesis of indeterminate potential (CHIP) and clonal cyto-penia of undetermined signi fi cance (CCUS) are de fi ned by somatic mutations in genes associated with myeloid neoplasms (MN) at a variant allele fraction (VAF) of 0.02 or ...

CAISC: A software to integrate copy number variations and single nucleotide mutations for genetic heterogeneity profiling and subclone detection by single-cell RNA sequencing

open access: yesBMC Bioinformatics, 2022
Background Although both copy number variations (CNVs) and single nucleotide variations (SNVs) detected by single-cell RNA sequencing (scRNA-seq) are used to study intratumor heterogeneity and detect clonal groups, a software that integrates these two ...
