While HCT outcomes have improved drastically over the years, patients and clinicians continue to face numerous survivorship challenges, such as relapse, graft-versus-host disease, and secondary malignancies. Recent literature suggests that clonal hematopoiesis (CH), the presence of a recurrent somatic mutation in hematopoietic cells, in HCT patients or donors may be associated with outcomes in autologous and allogeneic HCT. Herein, we perform a review of the literature and summarize reported associations between CH and clinical outcomes in HCT. For commonly reported outcomes, we used meta-analysis methods to provide estimates of effect sizes when combining results. A total of 32 articles with relevant and independent contributions were included, covering both autologous (N=19) and allogeneic (N=13) HCT. The articles report variable risk for developing outcomes according to CH characteristics, patient disease status, and method of HCT. Using meta-analysis of available results, HCT outcomes with statistically significant effects by CH status include therapy-related myeloid neoplasms (odds ratio =3.65; 95% confidence interval [CI]: 2.18-6.10) and overall survival (hazard ratio [HR]=1.38; 95% CI: 1.20-1.58) in autologous HCT and relapse (HR=0.80; 95% CI: 0.68-0.94) in allogeneic HCT. However, heterogeneity, biases, and limitations in the literature provide challenges for informing the translation of CH to clinical decision- making. We conclude with a call to action and discussion of next steps to build upon the current literature and provide granularity to the true clinical impact of CH in the setting of HCT.</p>","PeriodicalId":12964,"journal":{"name":"Haematologica","volume":" ","pages":"3952-3964"},"PeriodicalIF":8.2,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11609801/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141426733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During embryogenesis, hemogenic endothelium (HE) gives rise to hematopoietic stem and progenitor cells through the endothelial- to-hematopoietic transition (EHT). Understanding this process using iPSC is key to generating functional hematopoietic stem cells (HSC), a currently unmet challenge. In this study, we examined the role of the transcriptional factor GFI1B and its co-factor LSD1/KDM1A in EHT. To this end, we employed patient-derived iPSC lines with a dominant-negative dysfunctional GFI1B Q287* and irreversible pharmacological LSD1/KDM1A inhibition in healthy iPSC lines. The formation of HE remained unaffected; however, hematopoietic output was severely reduced in both conditions. Single-cell RNA sequencing (scRNAseq) performed on the CD144+/CD31+ population derived from healthy iPSC revealed similar expression dynamics of genes associated with in vivo EHT. Interestingly, LSD1/KDM1A inhibition in healthy lines before EHT resulted in a complete absence of hematopoietic output. However, uncommitted HE cells did not display GFI1B expression, suggesting a timed transcriptional program. To test this hypothesis, we ectopically expressed GFI1B in uncommitted HE cells, leading to downregulation of endothelial genes and upregulation of hematopoietic genes, including GATA2, KIT, RUNX1, and SPI1. Thus, we demonstrate that LSD1/KDM1A and GFI1B can function at distinct temporal points in different cellular subsets during EHT. Although GFI1B is not detected in uncommitted HE cells, its ectopic expression allows for partial hematopoietic specification. These data indicate that precisely timed expression of specific transcriptional regulators during EHT is crucial to the eventual outcome of EHT.</p>","PeriodicalId":12964,"journal":{"name":"Haematologica","volume":" ","pages":"3975-3988"},"PeriodicalIF":8.2,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11609818/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141497898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
