Ex Vivo Expansion of Hematopoietic Stem Cells in Two/ Three-Dimensional Co-Cultures with Various Source of Stromal Cells
[Tissue And Cell] The capacity of mesenchymal stem cells derived from different sources to support the expansion and maintenance of HSPC was compared with each other.
Integrative Single-Cell Expression and Functional Studies Unravels a Sensitization to Cytarabine-Based Chemotherapy Through HIF Pathway Inhibition in AML Leukemia Stem Cells
[Hemasphere] Scientists identified HIFhigh and HIFlow specific AML subgroups and provided a comprehensive single-cell expression atlas of 119,000 AML cells and AML-leukemia stem cells in paired diagnostic-relapse samples from these molecular subgroups.
Improving Hematopoietic Differentiation from Human Induced Pluripotent Stem Cells by the Modulation of Hippo Signaling with a Diarylheptanoid Derivative
[Stem Cell Research & Therapy] Researchers utilized a defined cocktail of cytokines without serum or feeder followed by the supplementation of ASPP 049 to produce hematopoietic stem/progenitor cells.
Case Report of Pediatric TTMV-Related Acute Promyelocytic Leukemia with Central Nervous System Infiltration and Rapid Accumulation of RARA-LBD Mutations
[Heliyon] Investigators presented a pediatric case that manifested as PML::RARA-negative acute promyelocytic leukemia with central nervous system involvement at onset. The patient experienced both intramedullary and extramedullary relapse one year after undergoing allogeneic hematopoietic stem cell transplantation.
Efficacy and Safety of Azacitidine in Pediatric Patients with Newly Diagnosed Advanced Myelodysplastic Syndromes Before Hematopoietic Stem Cell Transplantation in the AZA-JMML-001 Trial
[Pediatric Blood & Cancer] Scientists reported efficacy, pharmacokinetics, and safety data obtained in treatment-naive, pediatric patients with newly diagnosed advanced myelodysplastic syndromes receiving azacitidine in the AZA-JMML-001 study.
[FEBS Letters] The authors describe how chromobox (CBX) proteins dictate age-related changes in HSCs and stimulate oncogenic HSC fate decisions, either as canonical polycomb repressive complex 1 members or by alternative interactions, including non-epigenetic regulation.
[The Guardian] Two new but exceptionally rare Covid-19 vaccine side effects – a neurological disorder and inflammation of the spinal cord – have been detected by researchers in the largest vaccine safety study to date.
circRNA_SLC8A1 Promotes the Survival of Mycobacterium tuberculosis in Macrophages by Upregulating Expression of Autophagy-Related Protein SQSTM1/p62 to Activate the NF-κB Pathway
[Scientific Reports] Researchers found that miR-20b-5p expression was decreased, while sequestosome 1 (SQSTM1) protein expression was increased in a time- and dose-dependent manner in the human macrophage U937 in response to Mycobacterium tuberculosis infection.
[Hypertension Research] Scientists explored the mechanism and function of m6A in the pathogenesis of pulmonary arterial hypertension (PAH) and discuss the potential targeting of RNA m6A methylation modification as a treatment for PAH.
Extracellular Vesicles As Potential Biomarkers for Diagnosis and Recurrence Detection of Hepatocellular Carcinoma
[Scientific Reports] A prospective single-center cohort study including 37 HCC patients and 20 patients with non-malignant liver disease, as a control group, was conducted.
DNA of Neutrophil Extracellular Traps Binds TMCO6 to Impair CD8+ T Cell Immunity in Hepatocellular Carcinoma.
[Cancer Research] Scientists showed that DNA of neutrophil extracellular traps binds transmembrane and coiled-coil domains 6 (TMCO6) on CD8+ T cells to impair anti-tumor immunity and thereby promote HCC progression. TGF-β1 induced NET formation, which recruited CD8+ T cells.
Black Phosphorus-Based Nanoparticles Induce Liver Cancer Cell Mitochondrial Apoptosis and Immune Cell Tumor Infiltration for Enhancing Dendritic Cell Therapy
[Heliyon] The authors proposed a novel approach utilizing a combination of dendritic cell-based cellular immunotherapy and a photothermal nanoadjuvant black phosphorus nanoparticles.
