Optogenetic Suppression of Stem Cell-derived Cardiomyocyte Patch Engraftment Arrhythmias
Heart attacks affect millions of people worldwide by causing non-reversible damage to the heart. As a result, post-heart attack patients are much more susceptible to fatal complications such as heart failure. One potential therapy for post-heart attack patients is engrafting induced pluripotent stem cell-derived cardiomyocyte (iPSC-CM) patches to remuscularize scar tissue. However, these patches have been found to introduce potentially lethal arrhythmias. In my project, we seek to examine the efficacy of light-elicited currents (optogenetics) in suppressing such arrhythmias through computer simulations. If we establish that such optogenetic suppression is attainable and safe, we will provide a potential solution for experimental scientists to test further in large animals and possibly humans.
