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...

A Human Pluripotent Stem Cell-Based Somitogenesis Model Using Microfluidics

Study of Somite Formation Model Based on Microfluidic System Background and Research Motivation The formation of somites plays a crucial role in vertebrate embryonic development, significantly influencing the layout and functionality of the embryonic musculoskeletal system. Somite formation involves the segmentation of bilateral presomitic mesoderm...

Increased Cholesterol Synthesis Drives Neurotoxicity in Patient Stem Cell-Derived Model of Multiple Sclerosis

Lipid Metabolism Mechanisms in Neurodegenerative Diseases: A New Study on Multiple Sclerosis Multiple Sclerosis (MS) is a common inflammatory autoimmune demyelinating disease of the central nervous system (CNS). As the disease progresses, patients gradually experience neurological damage and disability. Although there have been advances in the trea...

A Distinct Metabolic and Epigenetic State Drives Trained Immunity in HSC-Derived Macrophages from Autoimmune Mice

Metabolic and Epigenetic States of HSC-Derived Macrophages in Autoimmune Diseases and Their Driving Mechanism of Trained Immunity Research Background In the context of autoimmune diseases (AD), studies have shown that prolonged activation of the immune system and inflammatory responses affect not only mature immune cells but also have profound effe...

Human Vascularized Macrophage-Islet Organoids to Model Immune-Mediated Pancreatic B Cell Pyroptosis upon Viral Infection

Background Since the outbreak of the COVID-19 pandemic, SARS-CoV-2 infection has not only affected the respiratory system but has also been closely related to metabolic diseases such as diabetes. Clinical observations have found occurrences of new-onset diabetes and worsening of existing diabetes among COVID-19 patients, particularly with an increa...

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 ...

The Landscape of Drug Sensitivity and Resistance in Sarcoma

Background Introduction This study explores the landscape of individual drug sensitivity and resistance in sarcoma patients. Sarcomas are a diverse group of tumors originating from mesenchymal tissue, including types such as osteosarcoma and soft tissue sarcoma, mostly affecting young people. Although the annual incidence of sarcomas is relatively ...

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...
