Platelets derive from megakaryocytes, which differentiate from hematopoietic stem/progenitor cells (HSPCs). Here, Qu et al show that platelet-derived microparticles carrying miR-1915-3p target HSPCs and promote megakaryopoiesis by suppressing RHOB ...

Biocatalytic Nanoregulators Restore Joint Redox‐Immune Homeostasis in Rheumatoid Arthritis
Mesenchymal stem cell‐derived extracellular vesicles (EVs) coat ruthenium‐loaded metal‐organic frameworks (Ru@ZrMOF), creating a targeted therapeutic (Ru@ZrMOF/EVs). This platform scavenges ROS, generates oxygen, and polarizes macrophages from M1 to M2, alleviating inflammation, inhibiting pannus, promoting cartilage repair, and downregulating HIF‐1α ...

The incredible journey: From megakaryocyte development to platelet formation [PDF]
Circulating blood platelets are specialized cells that prevent bleeding and minimize blood vessel injury. Large progenitor cells in the bone marrow called megakaryocytes (MKs) are the source of platelets.

Because of the scarcity of megakaryocytes in hematopoietic tissues, studying megakaryopoiesis heavily relies on the availability of appropriate cellular models.

Sabotaged Integral HSC Heterogeneity Underlies Essential Thrombocythemia Development
Single‐cell RNA sequencing (scRNA‐seq) maps how distinct driver mutations remodel hematopoietic stem cell (HSC) programs across essential thrombocythemia (ET). Comparative analysis uncovers both shared and subtype‐specific molecular signatures, identifies a triple‐negative (TN)‐associated HSC population enriched with malignant traits, and reveals the ...

miR-494-3p overexpression promotes megakaryocytopoiesis in primary myelofibrosis hematopoietic stem/progenitor cells by targeting SOCS6 [PDF]
Primary myelofibrosis (PMF) is a chronic Philadelphia-negative myeloproliferative neoplasm characterized by hematopoietic stem cell-derived clonal myeloproliferation, involving especially the megakaryocyte lineage.

CSF1R modulates megakaryopoiesis by targeting RUNX1 in immune thrombocytopenia
Immune thrombocytopenia (ITP) is an autoimmune bleeding disorder characterized by platelet destruction and defective megakaryopoiesis. However, the mechanisms underlying megakaryocyte (MK) dysfunction in ITP remain unclear. To address this, we performed

2-O, 3-O desulfated heparin mitigates murine chemotherapy- and radiation-induced thrombocytopenia
: Thrombocytopenia is a significant complication of chemotherapy and radiation therapy. Platelet factor 4 (PF4; CXCL4) is a negative paracrine of megakaryopoiesis.

Aging of the Hematopoietic System: Mechanisms, Consequences, and Systemic Interactions
Hematopoietic aging arises from intrinsic stem‐cell decline and bone‐marrow niche dysfunction, leading to myeloid skewing, immunosenescence, and clonal hematopoiesis. These changes drive systemic inflammation and multi‐organ disease, which in turn further disrupt the bone‐marrow niche and hematopoietic stem cell (HSC) function, creating a vicious cycle

Valproic acid (VPA) is one of the HDAC inhibitors used for the treatment of neurological disorders and hematological malignancies. Its role in self-renewal and proliferation of hematopoietic stem cells (HSCs) is well studied, but little is known about ...
