Disease Focus: Heart Disease


Mechanisms of Direct Cardiac Reprogramming

Heart disease is a leading cause of adult and childhood mortality. The underlying pathology is typically loss of heart muscle cells that leads to heart failure, or improper development of specialized cardiac muscle cells called cardiomyocytes during embryonic development that leads to congenital heart malformations. Because cardiomyocytes have little or no regenerative capacity after birth, […]

Elucidating Molecular Basis of Hypertrophic Cardiomyopathy with Human Induced Pluripotent Stem Cells

Familial hypertrophic cardiomyopathy (HCM) is the leading cause of sudden cardiac death in young people, including trained athletes, and is the most common inherited heart defect. Until now, studies in humans with HCM have been limited by a variety of factors, including variable environmental stimuli which may differ between individuals (e.g., diet, exercise, and lifestyle), […]

Characterization and Engineering of the Cardiac Stem Cell Niche

Despite therapeutic advances, cardiovascular disease remains a leading cause of mortality and morbidity in both California and Europe. New insights into disease pathology, models to expedite in vitro testing and regenerative therapies would have an enormous societal and financial impact. Although very promising, practical application of pluripotent stem cells or their derivatives face a number […]

Molecular Mechanisms Underlying Human Cardiac Cell Junction Maturation and Disease Using Human iPSC

Heart disease is the number one cause of death and disability in California and in the United States. Especially devastating is Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC), an inherited form of heart disease associated with a high frequency of arrhythmias and sudden cardiac death in young people, including young athletes, who despite their appearance of health […]

Antibody tools to deplete or isolate teratogenic, cardiac, and blood stem cells from hESCs

Purity is as important for cell-based therapies as it is for treatments based on small-molecule drugs or biologics. Pluripotent stem cells possess two properties: they are capable of self regeneration and they can differentiate to all different tissue types (i.e. muscle, brain, heart, etc.). Despite the promise of pluripotent stem cells as a tool for […]

Engineering microscale tissue constructs from human pluripotent stem cells

Tissues derived from stem cells can serve multiple purposes to enhance biomedical therapies. Human tissues engineered from stem cells hold tremendous potential to serve as better substrates for the discovery and development of new drugs, accurately model development or disease progression, and one day ultimately be used directly to repair, restore and replace traumatically injured […]

Transcriptional Regulation of Cardiac Pacemaker Cell Progenitors

Congenital and acquired defects of cardiac pacemakers are leading causes of morbidity and mortality in our society. Dysfunctions of the SA node and the lower conduction cells lead to a variety of complex arrhythmias that typically necessitate anti-arrhythmic therapy and implantation of devices. These treatments have significant limitations in their efficacy and risk-benefit ratio. Thus, […]

Optimization in the Identification, Selection and Induction of Maturation of Subtypes of Cardiomyocytes derived from Human Embryonic Stem Cells

Cardiovascular diseases remain the major cause of death in the western world. Stem and progenitor cell-derived cardiomyocytes (SPC-CMs) hold great promise for the myocardial repair. However, most of SPC-CMs displayed heterogeneous and immature electrophysiological phenotypes with substantial automaticity. Implanting these electrically immature and inhomogeneous CMs to the hearts would be arrhythmogenic and deleterious. Further optimization […]

Building Cardiac Tissue from Stem Cells and Natural Matrices

Congestive heart failure afflicts 4.8 million people, with 400,000 new cases each year. Myocardial infarction (MI), also known as a “heart attack”, leads to a loss of cardiac tissue and impairment of left ventricular function. Because the heart does not contain a significant number of multiplying stem, precursor, or reserve cells, it is unable to […]

Induction of cardiogenesis in pluripotent cells via chromatin remodeling factors

Heart disease is one of the biggest killers in the civilized world, and as populations age, this trend will increase dramatically. Currently the only way to treat failing hearts is with expensive and relatively ineffective drugs, or by heart transplantation. Ideally, we would like to be able to regenerate sick or dead heart tissue. The […]
