Selective Advantage of Mutant Stem Cells in Human Clonal Hematopoiesis Associated with Attenuated Response to Inflammation and Aging

Selective Advantage of Clonal Hematopoietic Mutant Stem Cells in Aging and Inflammatory Responses Background and Research Motivation Clonal Hematopoiesis (CH) is an aging-related phenomenon in the hematopoietic system, where hematopoietic stem cells (HSCs) acquire specific somatic mutations and undergo expansion, causing a particular mutated cell l...

Epitope Editing Protects Hematopoietic Cells from CD123 Immunotherapy for Acute Myeloid Leukemia

Epitope Prime Editing Shields Hematopoietic Cells from CD123 Immunotherapy: A Novel Therapeutic Strategy for Acute Myeloid Leukemia Research Background and Problem Statement Acute Myeloid Leukemia (AML) is a malignant blood disease characterized by the abnormal differentiation of myeloid hematopoietic stem and progenitor cells (HSPCs). Its incidenc...

Modeling the Atrioventricular Conduction Axis using Human Pluripotent Stem Cell-Derived Cardiac Assembloids

Modeling the Atrioventricular Conduction Axis Based on Human Pluripotent Stem Cell-Derived Cardiac Assembloids Research Background The atrioventricular (AV) conduction axis is responsible for electrical conduction between the atrium and the ventricle and is a core component of the cardiac electrophysiological system. The delay function of AV conduc...

Alveolar Regeneration by Airway Secretory-Cell-Derived p63+ Progenitors

Alveolar Regeneration: Role of p63+ Progenitor Cells Derived from Airway Secretory Cells Background Introduction Effective gas exchange in the lungs relies on the precise structure and function of various epithelial cells, distributed across two distinct structural regions: ductal airways and alveoli. When alveoli are damaged (e.g., due to inhaled ...

Marmoset and Human Trophoblast Stem Cells Differ in Signaling Requirements and Recapitulate Divergent Modes of Trophoblast Invasion

Differences in Signaling Requirements for Trophoblast Stem Cells between Humans and Marmosets Background and Research Motivation Embryo implantation and placenta formation are critical features of eutherian mammalian development. The trophoblast is a group of outer cells of the embryo that mediates the connection between the embryo and maternal tis...

Inflammation-Induced Epigenetic Imprinting Regulates Intestinal Stem Cells

Inflammation-Induced Epigenetic Imprinting and Intestinal Stem Cell Regulation In recent years, the scientific community has shown immense interest in the “memory” capabilities of non-immune cells, particularly the phenomenon where specific stem cells in adult tissues develop memory after undergoing inflammation, influencing their functionality. Ho...

A Primate-Specific Endogenous Retroviral Envelope Protein Sequesters SFRP2 to Regulate Human Cardiomyocyte Development

A Primate-Specific Endogenous Retroviral Envelope Protein Regulates Human Cardiomyocyte Development by Inhibiting SFRP2 Research Background and Significance Endogenous Retroviruses (ERVs) are remnants of ancient viral infections that integrated into the host genome and were inherited through the germline to modern human genomes during evolution. Th...

Disruption of TGF-β signaling pathway is required to mediate effective killing of hepatocellular carcinoma by human iPSC-derived NK cells

Background Introduction Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, with a five-year survival rate of less than 20%, and treatment options are extremely limited. Traditional targeted drug therapies, such as Sorafenib and other kinase inhibitors, have been used to treat HCC, but their efficacy is limited and diffi...

Network-Wide Risk Convergence in Gene Co-Expression Identifies Reproducible Genetic Hubs of Schizophrenia Risk

The Genetic Network Aggregation Mechanism for Schizophrenia Risk — Latest Research Interpretation from the Journal “Neuron” In recent years, genetic research on schizophrenia (SCZ) has made significant progress, particularly driven by genome-wide association studies (GWAS), revealing a large number of genetic variants associated with the disease. H...
