Human Stem Cell Use: iPS Cell
Correlated time-lapse imaging and single cell molecular analysis of human embryo development
We understand little about human development especially at the earliest stages. Yet human developmental biology is very important to stem cell biology and regenerative medicine for two reasons: 1) Understanding human developmental pathways especially of embryonic differentiation will inform our efforts to derive pluripotent stem cells and differentiate them to stable progenitors that are suitable […]
Discovery of mechanisms that control epigenetic states in human reprogramming and pluripotent cells
The CIRM Basic Biology Award III was developed to support basic research that enables the realization of the full potential of human stem cells and reprogrammed cells for therapies and as tools for biomedical innovation. This is particularly important since many fundamental issues related to the regulation of stem cell fate and reprogramming, especially with […]
Investigation of synaptic defects in autism using patient-derived induced pluripotent stem cells
Autism spectrum disorders (ASD) are a group of neurodevelopmental diseases that occur in as many as 1 in 150 children in the United States. Three hallmarks of autism are dysfunctional communication, impaired social interaction, and restricted and repetitive interests and activities. Even though no single genetic defect has been ascribed to having a causative role […]
Functional characterization of mutational load in nuclear reprogramming and differentiation
One of the most potentially powerful aspects of regenerative medicine is stem cell therapy. In this therapy, healthy tissues derived from stem cells will be implanted into patients with damaged tissue in order to restore function. However, there is currently a risk of immune rejection. Human induced pluripotent stem (hiPS) cells have the potential to […]
Triplet Repeat Instability in Human iPSCs
Over twenty human genetic diseases are caused by expansion of simple DNA sequences composed of repeats of three nucleotides (such as CAG, CTG, CGG and GAA) within essential genes. These repeats can occur within the region of a gene that encodes the protein, generally resulting in proteins with large stretches of repeats of just one […]
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 […]
Molecular determinants of accurate differentiation from human pluripotent stem cells
The use of human pluripotent stem cells for cell-based therapeutics is predicated on the ability to convert these cells into functional equivalents of those lost in disease or injury. However, there is only scant evidence that either human embryonic stem cells or human induced pluripotent stem cells make differentiated progeny that are functionally equivalent to […]
Understanding the role of LRRK2 in iPSC cell models of Parkinson’s Disease
The goal of this research is to utilize novel research tools to investigate the molecular mechanisms that cause Parkinson’s disease (PD). The proposed work builds on previous funding from CIRM that directed the developed patient derived models of PD. The majority of PD patients suffer from sporadic disease with no clear etiology. However some PD […]
