This review summarizes our knowledge about the interaction between HSCs and its inflammatory environment during life and questions how its disruption could affect the health of the hematopoietic system.Recent findings: The latest research demonstrates the direct role of inflammatory signals in promoting the emergence of the HSCs during development and in setting their steady-state activity in adults. They indicate that inflammatory patho-physiological conditions or immunological history could shape the structure and biology of the HSC compartment, therefore altering its overall fitness.Summary: Through instructive and/or selective mechanisms, the inflammatory environment seems to provide a key homeostatic signal for HSCs. Although the mechanistic basis of this complex interplay remains to be fully understood, its dysregulation has broad consequences on HSC physiology and the development of hematological diseases. As such, developing experimental models that fully recapitulate a normal basal inflammatory state could be essential to fully assess HSC biology in native conditions.","PeriodicalId":37444,"journal":{"name":"Current Stem Cell Reports","volume":"4 3","pages":"189-200"},"PeriodicalIF":1.4,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s40778-018-0131-y","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36916965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This concise review explores our current understanding of the mechanisms that influence the development of clonality with aging and its potential malignant and non-malignant clinical implications.Recent findings: Aging of the hematopoietic system results in phenotypic changes that favor clonal dominance. Cell-extrinsic factors provide additional selective pressures that further shape clonal architecture. Even so, small clones with candidate driver mutations appear to be ubiquitous with age and largely benign in the absence of strong selective pressures. Benign clonal expansion may compensate for the loss of regenerative HSC capacity as we age.Summary: CHIP is a marker of aging that reflects the biologic interplay between HSC aging and cell-extrinsic factors. The clinical significance of CHIP is highly variable and dependent on clinical context. Distinguishing the causal relationships and confounding factors that regulate clonal behavior will be essential to define the mechanistic role of CHIP in aging and potentially mitigate its clinical consequences.","PeriodicalId":37444,"journal":{"name":"Current Stem Cell Reports","volume":"4 3","pages":"209-219"},"PeriodicalIF":1.4,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s40778-018-0133-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37203126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While key components of the niche have been known for several years, recent advances have identified several additional cell types that regulate HSC in the bone marrow (BM). Here we review our current understanding of the components and dynamics of the HSC niche.Recent findings: While the niche has been considered a stable structure, recent advances clearly show that the niche is regulated in a dynamic manner to control HSC traffic and function. Moreover the niche can rapidly remodel in response to insults to the BM in a process controlled by positive and negative regulators.Summary: Multiple niche cells have been shown to be dynamically regulated by systemic and local signals to influence how the niche controls HSC function. Elucidating how different components of the niche coordinate to orchestrate HSC behavior is essential to understand how the hematopoietic system adjusts blood cell production to the demands of the body.","PeriodicalId":37444,"journal":{"name":"Current Stem Cell Reports","volume":"4 3","pages":"201-208"},"PeriodicalIF":1.4,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s40778-018-0132-x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37150701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, clinical IUCHT has failed except in cases where the fetus is severely immunocompromised. The current review examines recent studies of engraftment barriers stemming from either the fetal or maternal immune system.Recent findings: New reports have illuminated roles for maternal humoral and cellular immunity and fetal innate cellular immunity in the resistance to allogeneic IUHCT. These experimental findings have inspired new approaches to overcome these barriers. Despite these advances, postulates regarding a maternal immune barrier to IUHCT provide an inadequate explanation for the well-documented clinical success only in the treatment of fetal immunodeficiency with normal maternal immunity.Summary: Characterization of the maternal and fetal immune response to allogeneic IUHCT provides new insight into the complexity of prenatal tolerance. Future work in this area should aim to provide a unifying explanation for the observed patterns of success and failure with clinical IUHCT.","PeriodicalId":37444,"journal":{"name":"Current Stem Cell Reports","volume":"4 2","pages":"182-187"},"PeriodicalIF":1.4,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s40778-018-0129-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37057229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Long noncoding RNAs are emerging as key, multi-faceted regulators of gene expression. This review explores the function of lncRNAs in the control of HSC homeostasis and hematopoietic differentiation.Recent findings: Multiple lncRNAs have been implicated in maintaining HSC stemness and enabling progenitors to carry out the correct programs of lineage differentiation. Specific lncRNAs have been identified that regulate the differentiation of multipotent progenitors into terminally differentiated blood cells. These lncRNAs predominantly act by assisting master regulators that drive specific differentiation programs, either by enhancing or repressing the transcription of particular genomic loci.Summary: Long noncoding RNAs contribute to the correct differentiation and maturation of various hematopoietic lineages by assisting with the activation of transcriptional programs in a time- and cell-dependent manner.","PeriodicalId":37444,"journal":{"name":"Current Stem Cell Reports","volume":"4 2","pages":"158-165"},"PeriodicalIF":1.4,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s40778-018-0130-z","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36665758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
