Summary

Human induced pluripotent stem cells (hiPSCs) have driven a paradigm shift in the modeling of human disease; the ability to reprogram patient-specific cells holds the promise of an enhanced understanding of disease mechanisms and phenotypic variability, with applications in personalized predictive pharmacology/toxicology, cell therapy and regenerative medicine. This research will collect blood or skin biopsies from patients and healthy controls for the purpose of generating cell and tissue models of Mendelian heritable forms of heart disease focusing on cardiomyopathies, channelopathies and neuromuscular diseases. Cardiomyocytes derived from hiPSCs will provide a ready source of disease specific cells to study pathogenesis and therapeutics.

Detailed description

Further study details as provided by Gordon F. Tomaselli, Johns Hopkins University: Biospecimen Retention: Blood or tissue samples, hiPSCs and cardiomyocytes reprogrammed from hiPSCs Eligible patients will be approached and the study will be explained in full as a part of obtaining informed consent for the study. The subjects will have an opportunity to ask questions about the study. Control subjects, often but not exclusively family member that meet the eligibility criteria will undergo a similar procedure for informed consent. Subjects will be evaluated in clinic and will have a 1-3 mm skin biopsy or blood draw (30 cc). The subjects will be asked about their medical history during the clinic visit but this information will not be transmitted to the research laboratories where the iPSCs are generated and re-programmed, only the disease genotype will be associated with the samples. The samples that will be frozen and stored are whole blood, white blood cells, skin biopsies, hiPSCs and reprogrammed cardiomyocytes.
