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: 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 ...
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 ...
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...
The Role of Embryonic Macrophages in Human Pancreatic Development Background and Research Motivation Pancreatic development involves complex interactions between various cell types. In recent years, the influence of multiple cells within the pancreatic microenvironment has gained attention; however, the role of immune cells in pancreatic organogene...
Research Background The maintenance and repair of the hematopoietic system are crucial for the continuation of life and health in an organism. As the foundation of the hematopoietic system, the stability of hematopoietic stem cells (HSCs) is particularly important. The maintenance of the HSC pool relies on intrinsic and extrinsic factors, among whi...
Persistent Expression of Amphiregulin (AREG) in Intermediate Alveolar Stem Cells Drives Progressive Pulmonary Fibrosis Background Fibrotic diseases are a leading cause of up to 45% of deaths in developed countries. Pulmonary fibrosis is a disease characterized by alveolar structure damage and impaired gas exchange, with Idiopathic Pulmonary Fibrosi...
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...
Multilayered Tissue Construction of a Micro-intestinal System Reproduces Mesenchymal Flow Research Background In recent years, constructing in vitro models of the human small intestine has made significant progress; however, fully replicating its complex structural and functional characteristics remains challenging. The goal of micro-intestinal tis...
Research Background and Objective As individuals age, hematopoietic stem cells (HSCs) progressively accumulate in the bone marrow, exhibiting metabolic resilience under various stress conditions. This metabolic resilience provides an aging advantage for HSCs, enabling them to maintain cell viability even under low metabolic conditions. Although agi...
