Standard: Human gastric cancer organoids.

Gastric cancer is one of the most common malignancies with poor prognosis. The use of organoids to simulate gastric cancer has rapidly developed over the past several years. Patient-derived gastric cancer organoids serve as in vitro models that closely mimics donor characteristics, offering new opportunities for both basic and applied research.

Midterm follow-up results of implantation of a fully biodegradable ventricular septal defect occluder.

Objectives: Ventricular septal defect (VSD) is a prevalent congenital cardiac anomaly. By enhancing the occluder design and optimizing procedural approaches, the indications for VSD closure can be broadened while minimizing associated complications. The utilization of fully biodegradable occluder holds promising potential in resolving conduction block issues encountered during VSD closure.

Development and disease-specific regulation of RNA splicing in cardiovascular system.

Alternative splicing is a complex gene regulatory process that distinguishes itself from canonical splicing by rearranging the introns and exons of an immature pre-mRNA transcript. This process plays a vital role in enhancing transcriptomic and proteomic diversity from the genome. Alternative splicing has emerged as a pivotal mechanism governing complex biological processes during both heart development and the development of cardiovascular diseases.

Establishment of a human induced pluripotent stem cell line from a patient with dilated cardiomyopathy.

Dilated cardiomyopathy (DCM) is one of the main causes of sudden cardiac death and heart failure and is the leading indication for cardiac transplantation worldwide. Mutations in dozens of cardiac genes have been connected to the development of DCM including the Troponin T2 gene (TNNT2). Here, we generated a human induced pluripotent stem cells (hiPSCs) from a DCM patient with a familial history that carries a missense mutation in TNNT2.

Thiamine-modified metabolic reprogramming of human pluripotent stem cell-derived cardiomyocyte under space microgravity.

During spaceflight, the cardiovascular system undergoes remarkable adaptation to microgravity and faces the risk of cardiac remodeling. Therefore, the effects and mechanisms of microgravity on cardiac morphology, physiology, metabolism, and cellular biology need to be further investigated. Since China started constructing the China Space Station (CSS) in 2021, we have taken advantage of the Shenzhou-13 capsule to send human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) to the Tianhe core module of the CSS.

Generation of a human induced pluripotent stem cell line harboring heteroplasmic m.3243A > G mutation in MT-TL1 gene.

Generation of human vascularized and chambered cardiac organoids for cardiac disease modelling and drug evaluation.

Human induced pluripotent stem cell (hiPSC)-derived cardiac organoids (COs) have shown great potential in modelling human heart development and cardiovascular diseases, a leading cause of global death. However, several limitations such as low reproducibility, limited vascularization and difficulty in formation of cardiac chamber were yet to be overcome. We established a new method for robust generation of COs, via combination of methodologies of hiPSC-derived vascular spheres and directly differentiated cardiomyocytes from hiPSCs, and investigated the potential application of human COs in cardiac injury modelling and drug evaluation.

Generation of human induced pluripotent stem cell line from a patient with restrictive cardiomyopathy.

Restrictive cardiomyopathy (RCM) is a rare cardiomyopathy characterized by diastolic dysfunction, which affects cardiac systolic function. We successfully established human induced pluripotent stem cells (hiPSCs) from peripheral blood mononuclear cells of 24-year-old male with restrictive cardiomyopathy (RCM). The patient-derived hiPSCs carried heterozygous mutation of CRYAB gene (c.

Conserved mechanisms of self-renewal and pluripotency in mouse and human ESCs regulated by simulated microgravity using a 3D clinostat.

Embryonic stem cells (ESCs) exhibit unique attributes of boundless self-renewal and pluripotency, making them invaluable for fundamental investigations and clinical endeavors. Previous examinations of microgravity effects on ESC self-renewal and differentiation have predominantly maintained a descriptive nature, constrained by limited experimental opportunities and techniques. In this investigation, we present compelling evidence derived from murine and human ESCs, demonstrating that simulated microgravity (SMG)-induced stress significantly impacts self-renewal and pluripotency through a previously unidentified conserved mechanism.

Mitochondrial diseases and mtDNA editing.

Mitochondrial diseases are a heterogeneous group of inherited disorders characterized by mitochondrial dysfunction, and these diseases are often severe or even fatal. Mitochondrial diseases are often caused by mitochondrial DNA mutations. Currently, there is no curative treatment for patients with pathogenic mitochondrial DNA mutations.

ASH2L regulates postnatal neurogenesis through Onecut2-mediated inhibition of TGF-β signaling pathway.

The ability of neural stem/progenitor cells (NSPCs) to proliferate and differentiate is required through different stages of neurogenesis. Disturbance in the regulation of neurogenesis causes many neurological diseases, such as intellectual disability, autism, and schizophrenia. However, the intrinsic mechanisms of this regulation in neurogenesis remain poorly understood.
