- W3133669010 abstract "Abstract Hematopoietic stem cells (HSCs) must ensure adequate blood cell production following distinct external stressors. A comprehensive understanding of in vivo heterogeneity and specificity of HSC responses to external stimuli is currently lacking. We performed single-cell RNA sequencing (scRNA-Seq) on functionally validated mouse HSCs and LSK (Lin-, c-Kit+, Sca1+) progenitors after in vivo perturbation of niche signals interferon, granulocyte-colony stimulating factor (G-CSF), and prostaglandin. We identified six HSC states that are characterized by enrichment but not exclusive expression of marker genes. Niche perturbations induce novel and rapid transitions between these HSC states. Differential expression analysis within each state revealed HSC- and LSK-specific molecular signatures for each perturbation. Chromatin analysis of unperturbed HSCs and LSKs by scATAC-Seq revealed HSC-specific, cell intrinsic predispositions to niche signals. We compiled a comprehensive resource of HSC- and progenitor-specific chromatin and transcriptional features that represent important determinants of regenerative potential during stress hematopoiesis." @default.
