Slow cycling and durable Flt3+ progenitors contribute to hematopoiesis under native conditions. J Exp Med 2024; 221:e20231035. [PMID: 37910046 PMCID: PMC10620607 DOI: 10.1084/jem.20231035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 09/18/2023] [Accepted: 10/13/2023] [Indexed: 11/03/2023] Open
Abstract
The dynamics of the hematopoietic flux responsible for blood cell production in native conditions remains a matter of debate. Using CITE-seq analyses, we uncovered a distinct progenitor population that displays a cell cycle gene signature similar to the one found in quiescent hematopoietic stem cells. We further determined that the CD62L marker can be used to phenotypically enrich this population in the Flt3+ multipotent progenitor (MPP4) compartment. Functional in vitro and in vivo analyses validated the heterogeneity of the MPP4 compartment and established the quiescent/slow-cycling properties of the CD62L- MPP4 cells. Furthermore, studies under native conditions revealed a novel hierarchical organization of the MPP compartments in which quiescent/slow-cycling MPP4 cells sustain a prolonged hematopoietic activity at steady-state while giving rise to other lineage-biased MPP populations. Altogether, our data characterize a durable and productive quiescent/slow-cycling hematopoietic intermediary within the MPP4 compartment and highlight early paths of progenitor differentiation during unperturbed hematopoiesis.

Retinoid X receptor promotes hematopoietic stem cell fitness and quiescence and preserves hematopoietic homeostasis. Blood 2023; 141:592-608. [PMID: 36347014 PMCID: PMC10082360 DOI: 10.1182/blood.2022016832] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 10/20/2022] [Accepted: 10/30/2022] [Indexed: 11/10/2022] Open
Abstract
Hematopoietic stem cells (HSCs) balance self-renewal and differentiation to maintain hematopoietic fitness throughout life. In steady-state conditions, HSC exhaustion is prevented by the maintenance of most HSCs in a quiescent state, with cells entering the cell cycle only occasionally. HSC quiescence is regulated by retinoid and fatty-acid ligands of transcriptional factors of the nuclear retinoid X receptor (RXR) family. Herein, we show that dual deficiency for hematopoietic RXRα and RXRβ induces HSC exhaustion, myeloid cell/megakaryocyte differentiation, and myeloproliferative-like disease. RXRα and RXRβ maintain HSC quiescence, survival, and chromatin compaction; moreover, transcriptome changes in RXRα;RXRβ-deficient HSCs include premature acquisition of an aging-like HSC signature, MYC pathway upregulation, and RNA intron retention. Fitness loss and associated RNA transcriptome and splicing alterations in RXRα;RXRβ-deficient HSCs are prevented by Myc haploinsufficiency. Our study reveals the critical importance of RXRs for the maintenance of HSC fitness and their protection from premature aging.

Abstract
This review is focused on the cellular dynamics and genomic programming of plasma cell (PC) precursors that arise during germinal center (GC) B cell responses in secondary lymphoid organs (SLOs) and give rise to PCs in the bone marrow. Considerable progress has been made in the phenotypic characterization of circulating and bone marrow PC precursors as well as their differentiated short-lived (SLPC) and long-lived (LLPC) counterparts, in the context of model antigen and vaccine responses. Importantly, it has been possible to infer the temporal dynamics of generation of PC precursors during a GC response. However, the nature of the PC precursors at their site of generation in SLOs, and their signaling and genomic states, remain to be elucidated. Our synthesis draws upon experimental studies conducted in murine models as well as in humans, the latter complemented with cell culture manipulations of PCs and their precursors. By integration of the studies in murine and human systems, which are being accelerated by new genomic methodologies, we highlight insights and hypotheses concerning the generation of PCs. This framework can be extended and explored from both fundamental and translational standpoints.
