摘要

A unique subset of CD86(-) HSCs was previously discovered in mice that were old or chronically stimulated with lipopolysaccharide. Functionally defective HSCs were also present in those animals, and we now show that CD86(-) CD150(+) CD48(-) HSCs from normal adult mice are particularly poor at restoring the adaptive immune system. Levels of the marker are high on all progenitors with lymphopoietic potential, and progressive loss helps to establish relations between progenitors corresponding to myeloid and erythroid lineages. CD86 represents an important tool for subdividing HSCs in several circumstances, identifying those unlikely to generate a full spectrum of hematopoietic cells. (Blood. 2012;119(21): 4889-4897)

Erythropoietin directly remodels the clonal composition of murine hematopoietic multipotent progenitor cells

Almut S. Eisele, Jason Cosgrove, Aurelie Magniez, Emilie Tubeuf, Sabrina Tenreira Bento, Cecile Conrad, Fanny Cayrac, Tamar Tak, Anne-Marie Lyne, Jos Urbanus, Leila Perie

Summary: This study used cellular barcoding to trace the differentiation of mouse hematopoietic stem and progenitor cells (HSPCs) after exposure to EPO. The researchers found that EPO can directly act on multipotent progenitor cells (MPP) and modulate fate by remodeling the clonal composition of the MPP pool.

Encapsulation of murine hematopoietic stem and progenitor cells in a thiol-crosslinke d maleimide-functionalize d gelatin hydrogel

Aidan E. Gilchrist, Julio F. Serrano, Mai T. Ngo, Zona Hrnjak, Sanha Kim, Brendan A. C. Harley

Summary: Biomaterial platforms are crucial in stem cell biomanufacturing, with GelMAL hydrogel providing a versatile route for encapsulating stem cell populations and mimicking the bone marrow niche. The maleimide-functionalized gelatin allows for stable crosslinking without reactive oxide species generation, demonstrating potential for artificial stem cell niche construction.

Maternal dendritic cells influence fetal allograft response following murine in-utero hematopoietic stem cell transplantation

Karthikeyan Kandasamy, Nuryanti Binti Johana, Lay Geok Tan, Yvonne Tan, Julie Su Li Yeo, Nur Nazneen Binte Yusof, Zhihui Li, Jiayu Koh, Florent Ginhoux, Jerry K. Y. Chan, Mahesh Choolani, Citra N. Z. Mattar

Summary: Maternal immune cells trafficked into the recipient's body through the placenta can directly influence immune responses to donor cells, limiting donor cell chimerism. Depleting maternal dendritic cells reduces recipient alloresponsiveness and enhances donor cell chimerism, suggesting a novel approach to improving donor cell tolerance.

Thioredoxin-1 regulates self-renewal and differentiation of murine hematopoietic stem cells through p53 tumor suppressor

Shaima Jabbar, Parker Mathews, Xiaobei Wang, Pasupathi Sundaramoorthy, Emily Chu, Sadhna O. Piryani, Shengli Ding, Xiling Shen, Phuong L. Doan, Yubin Kang

Summary: This study reveals that the thioredoxin-1 (TXN1)-TP53 axis plays a regulatory role in the biological functions of hematopoietic stem/progenitor cells (HSPCs). Deletion of TXN1 activates the TP53 signaling pathway and impairs the capacity of HSPCs to reconstitute hematopoiesis. Moreover, knockout of TXN1 renders HSPCs more sensitive to radiation, while treatment with recombinant TXN1 promotes the proliferation and expansion of HSPCs.

Optimized Intracellular Staining Reveals Heterogeneous Cytokine Production Ability of Murine and Human Hematopoietic Stem and Progenitor Cells

Shufeng Luo, Huiling Lin, Lan Zhu, Hai-Tian Chen, Siqian Yang, Jinheng Li, Mingyu Liu, Limin Zheng, Chong Wu

Summary: Under stress conditions, HSPCs can interpret danger signals into cytokine signals to modify hematopoietic output. A flow cytometry-based method was developed to assess intracellular cytokines in HSPCs, revealing distinct regulatory modes of cytokine production depending on subset, cytokine, disease, organ, and species. This technical advance helps to better understand HSPC heterogeneity based on differential cytokine production.

Murine bone marrow mesenchymal stromal cells have reduced hematopoietic maintenance ability in sickle cell disease

Alice Tang, Ana Nicolle Strat, Mahmudur Rahman, Helen Zhang, Weili Bao, Yunfeng Liu, David Shi, Xiuli An, Deepa Manwani, Patricia Shi, Karina Yazdanbakhsh, Avital Mendelson

Summary: Studies have found that murine SCD MSCs exhibit altered gene signatures, reduced stem cell properties, and increased oxidative stress, leading to decreased HSC maintenance ability. The activation of Toll-like receptor-4 through p65 in MSCs further exacerbates MSC dysfunction in SCD.

Hematopoietic Jagged1 is a fetal liver niche factor required for functional maturation and engraftment of fetal hematopoietic stem cells

Lijian Shao, Na Yoon Paik, Mark A. Sanborn, Thilinie Bandara, Anjali Vijaykumar, Kilian Sottoriva, Jalees Rehman, Cesar Nombela-Arrieta, Kostandin V. Pajcini

Summary: Notch signaling is crucial for the emergence and development of definitive hematopoietic stem cells (HSCs) in the embryo and fetal liver. This study reveals endothelial Jagged1 (Jag1) as a critical factor in early fetal liver vascular development but not essential for fetal HSC expansion. Jag1 is expressed in various hematopoietic cells in the fetal liver, including HSCs, but lost in adult bone marrow HSCs. Deletion of hematopoietic Jag1 does not impact fetal liver development, but results in a significant transplantation defect in fetal liver HSCs.

Treg-expressed CTLA-4 depletes CD80/CD86 by trogocytosis, releasing free PD-L1 on antigen-presenting cells

Murat Tekguc, James Badger Wing, Motonao Osaki, Jia Long, Shimon Sakaguchi

Summary: Regulatory T cells reduce the expression of CD80/CD86 on antigen-presenting cells through CTLA-4-dependent trogocytosis, inhibiting T cell immune responses. This mechanism can have dual suppressive effects, limiting CD80/CD86 costimulation to naive T cells and increasing free PD-L1 available for the inhibition of PD-1-expressing effector T cells.

The Reconstitution Dynamics of Cultivated Hematopoietic Stem Cells and Progenitors Is Independent of Age

Frauke Gotzhein, Tim Aranyossy, Lars Thielecke, Tanja Sonntag, Vanessa Thaden, Boris Fehse, Ingo Mueller, Ingmar Glauche, Kerstin Cornils

Summary: In this study, a murine model of HSCT was used to investigate the contribution of different hematological subpopulations to the reconstitution process and the impact of age on this process. The results showed that hematopoietic stem cells and multipotent progenitors played a major role in reconstitution, independent of age. The reconstitution patterns were stable in all age groups. These findings support the expansion of HSCT in older individuals as a promising strategy for treating hematological diseases.

Utilizing Low Oxygen Tension to Reduce Hematopoietic Cells in Murine Bone Marrow Stromal Cell Cultures

Wendi Guo, Colleen Wu

Summary: Currently, there is a lack of universally accepted markers for isolating skeletal stem cells (SSCs). Therefore, researchers continue to use bone marrow-derived mesenchymal stem cells (BMSCs) as a model to study SSCs and multipotent mesenchymal progenitors (MMPs). However, the common isolation procedures for BMSCs often result in a high percentage of hematopoietic cells, which can complicate data interpretation. In this study, a method using low oxygen tension or hypoxia is described to selectively eliminate CD45+ cells in BMSC cultures, reducing hematopoietic contaminants and enhancing MMPs and putative SSCs.

Hematopoietic cell-mediated dissemination of murine cytomegalovirus is regulated by NK cells and immune evasion

Summary: This study reveals that cytomegalovirus relies on hematopoietic cells for dissemination after infection, while cell-mediated immune responses restrict the virus to infected hematopoietic cells during dissemination.

Elucidating the mitochondrial function of murine lymphocyte subsets and the heterogeneity of the mitophagy pathway inherited from hematopoietic stem cells

Haoyue Liang, Weichao Fu, Wenying Yu, Zhijie Cao, Ertao Liu, Fanfan Sun, Xiaodong Kong, Yingdai Gao, Yuan Zhou

Summary: This study compares the mitochondrial functions of different subsets of lymphocytes at different stages of differentiation and activation. B cells were found to have relatively high mitochondrial metabolic activity, while mature B cells showed lower levels. Naive CD4(+) T cells also exhibited relatively high mitochondrial metabolism. Memory CD8(+) T cells had high mitochondrial mass and membrane potential but low mitophagy levels. The study also analyzed the involvement of autophagy-related genes in different lymphocyte subsets, highlighting the heterogeneity of mitophagy pathways.
