CD150high CD4 T cells and CD150high regulatory T cells regulate hematopoietic stem cell quiescence via CD73

Haematologica, 2019
Various extrinsic signals tightly control hematopoietic stem cell quiescence. Our recent study showed that hematopoietic stem cells are regulated by a special FoxP3+ regulatory T-cell population with high expression of a hematopoietic stem cell marker ...

Tropomyosin 1 Promotes Platelet Adhesion and Clot Contraction Separate from Its Roles in Developmental Hematopoiesis

Advanced Science, EarlyView.
ABSTRACT Genome‐wide association studies (GWAS) link the Tropomyosin 1 (Tpm1) locus to quantitative blood trait variation, but related mechanisms are unclear. Tpm1 encodes an actin‐binding protein that regulates actin filament diversity, cell adhesion, signaling, and actomyosin contractility.

A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

Advanced Science, EarlyView.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.

P121 | A VALID PREDICTIVE APPROACH IN PATIENTS WITH CHRONIC LYMPHOCYTIC LEUKEMIA: COMBINATION OF MULTIGENE PROFILING AND HIGH-SENSITIVITY MINIMAL RESIDUAL DISEASE ASSESSMENT

Haematologica
The correlation between the genetic heterogeneity of CLL and clinical diversity still remains unclear, although Next Generation Sequencing (NGS) approaches have contributed to the improvement of such knowledge.

U-shaped association of the stress hyperglycemia ratio with all-cause mortality and premature death in patients with cardiovascular disease: a cohort study

Diabetology & Metabolic Syndrome
Background The stress hyperglycemia ratio (SHR) is recognized as a significant indicator of relative hyperglycemia that has demonstrated to correlate with poor outcomes, including elevated mortality rates in individuals facing severe acute conditions ...

Human Mesenchymal Stem/Stromal Cells from Umbilical Cord Blood and Placenta Exhibit Similar Capacities to Promote Expansion of Hematopoietic Progenitor Cells In Vitro

Stem Cells International, 2017
Mesenchymal stem/stromal cells (MSCs) from bone marrow (BM) have been used in coculture systems as a feeder layer for promoting the expansion of hematopoietic progenitor cells (HPCs) for hematopoietic cell transplantation.

Interleukin-1 regulates hematopoietic progenitor and stem cells in the midgestation mouse fetal liver

Haematologica, 2009
Background Hematopoietic progenitors are generated in the yolk sac and aorta-gonad-mesonephros region during early mouse development. At embryonic day 10.5 the first hematopoietic stem cells emerge in the aorta-gonad-mesonephros.

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

P094 | HIGH-SENSITIVITY DETECTION OF LOW ALLELE FREQUENCY V617F VARIANT IN THE JAK2 GENE USING DIGITAL PCR (DPCR): A NOVEL TOOL FOR DIAGNOSIS OF MYELOPROLIFERATIVE NEOPLASMS

Haematologica
Accurate quantification of the V617F variant in the JAK2 gene using highly sensitive technologies is crucial for the diagnosis, therapeutic monitoring and prognostic assessment of patients with myeloproliferative neoplasms (MPNs).

Saikogenin A improves ethanol-induced liver injury by targeting SIRT1 to modulate lipid metabolism

Communications Biology
Chronic alcohol consumption can lead to alcohol live disease (ALD). Steatosis is a critical hallmark of ALD, making it an important stage for therapeutic intervention.
