Megakaryocyte emperipolesis mediates membrane transfer from intracytoplasmic neutrophils to platelets

eLife, 2019
Bone marrow megakaryocytes engulf neutrophils in a phenomenon termed emperipolesis. We show here that emperipolesis is a dynamic process mediated actively by both lineages, in part through the β2-integrin/ICAM-1/ezrin pathway.

Flow Cytometry‐Guided Diagnosis of Cortical T‐Lymphoblastic Lymphoma Presenting With a Massive Mediastinal Mass and Borderline Bone Marrow Involvement

Journal of Clinical Laboratory Analysis, EarlyView.
ABSTRACT Background T‐cell lymphoblastic lymphoma (T‐LBL) and T‐cell acute lymphoblastic leukemia (T‐ALL) are considered a single biological entity, distinguished primarily by the extent of bone marrow infiltration. This distinction becomes diagnostically challenging in patients with borderline marrow blast counts and predominantly extramedullary ...

Murine hematopoietic progenitor cell lines with erythroid and megakaryocyte potential

Nature Communications
Red blood cells and platelets derive from bi-potential bone marrow megakaryocyte-erythroid progenitors, but their study is constrained by cell scarcity and limited experimental systems.

Biological Specificities of Fetal Anemia Induced by Parvovirus B19 Infection

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To describe the biological fetal parameters in cases of severe anemia induced by parvovirus B19 (B19V) infection. Method A retrospective single center study was conducted including cases of fetal anemia due to B19V receiving in utero transfusion (IUT) from January 2011 to May 2024.

Proteomic Analysis of Mixed Cell Membrane Extracts From Triple‐Negative Breast Cancer Cell Lines Revealed Broad Metabolic Reprogramming Associated With Tumor Progression

PROTEOMICS, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) represents the most aggressive subtype with limited therapeutic options and the poorest clinical outcomes. Using high‐resolution nUPLC‐QTOF‐MS/MS, we performed comprehensive proteomic profiling of TNBC cell lines representing disease progression stages: HCC‐1937 (stage IIB), HCC‐1599 (stage IIIA), and MDA ...

Cell‐Based Micro/Nanorobots: From Living Carriers to Living Therapeutic Specialists

SmartBot, EarlyView.
Cell‐based micro/nanorobots integrate evolutionarily acquired biological intelligence with engineered capabilities, offering new opportunities for precision medicine in vivo. However, the complex physiological environments of different organs pose significant challenges to their clinical translation.

Effect of PEG-recombinant human megakaryocyte growth and development factor (PEG-rHuMGDF) on growth and differentiation of the HEL cell line

Haematologica, 1998
BACKGROUND AND OBJECTIVE: Thrombopoietin has been established as the major regulator of megakaryocyte and platelet production. In this study we evaluated the effects of PEG-recombinant human megakaryocyte growth and development factor (PEG-rHuMGDF), a ...

Thrombocytosis and tumour distribution predict outcome in dogs with hepatocellular carcinoma: A multi‐institutional retrospective analysis

Veterinary Record, EarlyView.
Abstract Background Hepatocellular carcinoma (HCC) is the most common canine hepatobiliary tumour. This study aimed to determine which criteria influenced outcome of HCC in a modern population of dogs across eight institutions. Methods The medical records of 106 dogs with HCC were retrospectively reviewed.

Dietary CoQ10 Ameliorates Age-Related Megakaryocyte Dysfunction via COPS3-Mediated Activation of Autophagy. [PDF]

Aging Cell
Dietary CoQ10 improves megakaryocyte maturation and polyploidization and reduces platelet hyperreactivity in naturally aged mice, while experiments in senescent Meg‐01 cells demonstrate enhanced autophagic flux and identify COPS3 as a contributing, but not, mediator.
