The use of human stem cell lines derived from persons with Autism Spectrum Disorder (ASD) provides a unique opportunity to model brain growth and potential to regain brain activity for treatment. Our lab has previously used stem cells to derive 3D cardiomyocytes to examine cardiovascular disease as well as kidney organoids and macrophages to study kidney disease. Using techniques our lab has learned using these stem cell models have prepared us to examine cell communication in mutated neurons. We will …

A Humanized Hypertrophic Cardiomyopathy Model To Elucidate Molecular Mechanism In Disease Pathology, Ragavi Vijayakumar, Maxine Hong

The International Student Science Fair 2018

Hypertrophic cardiomyopathy (HCM), that clinically manifests as an enlarged heart is a highly prevalent cardiac disorder with propensity towards arrhythmia-induced sudden cardiac death. The mechanism of HCM remains poorly defined, necessitating further understanding of the disease for improved therapeutic strategies. As it is challenging to obtain cardiac biopsies from human subjects, using induced pluripotent stem cells technology, we generated cardiomyocytes (CMs) in a dish from HCM patients. These HCM-CMs presented the clinical manifestation in that they were significantly larger in size in comparison to control (healthy)-CMs. Furthermore, gene expression profiling of cardiac ion channels revealed increased transcripts encoding for calcium …
