But they turn out to have irregular internal structures, making them difficult to analyze. That\u2019s where Lejeune\u2019s work comes in. \u201cThe initial step is not artificial intelligence\u201d she says. \u201cThis work is mainly computational methods that are a step <em>before <\/em>it\u2019d be appropriate to apply AI.\u201d<\/p>\n<p>The program that Lejeune and colleagues in her lab have developed, and that they hope to improve with the AHA funding, analyzes video of hiPSC-CMs beating. The Sarc-Graph software makes it possible to quantify properties such as the amount and direction of beating cell contraction, Lejeune explains, or variation in behavior across different parts of the cell <em>(see example below)<\/em>.<\/p>\n<div class=\"responsive-video responsive-youtube\"><iframe loading=\"lazy\" title=\"Example_Cell_Movie\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/6kobht1OSk8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/div>\n<p>\u201cThe software will allow you to process movies to subsequently make comparisons between different cells or interface with a machine learning algorithm and get results that are interpretable,\u201d Lejeune says. \u201cInterpretable from both a scientific perspective and a high-stakes applications perspective,\u201d in the sense that decisions about patient care could be based on the output of the software.<\/p>\n<p>\u201cOne of the big questions is: Are the things you observe in these cells ultimately relevant to the way things actually behave in the body?\u201d says Lejeune. For example, some drugs that treat other diseases, such as cancer, can cause the heart to stop beating in a regular rhythm. \u201cSo can we observe something in these [hiPSC-CM] cells that will predict the heart\u2019s behavior in the body? And really, the software we\u2019re working on would enable that kind of discovery.\u201d<\/p>\n<p>Lejeune\u2019s colleagues in the study that formed the basis for her AHA Career Development research were Professor <a href=\"https:\/\/www.bu.edu\/eng\/profile\/christopher-chen-m-d-ph-d\/\">Christopher Chen<\/a> (BME, MSE), ME MS student Bill Zhao, and then-PhD student Kehan Zhang (\u201920), now a postdoc at MIT. \u201cWe\u2019re able to bring together expertise in computational modeling and biomedical engineering,\u201d says Lejeune. \u201cWe wouldn\u2019t have been able to do the work we\u2019ve done without access to the research community at BU, and now this [AHA] funding will help us develop this open source software to the benefit of the broader research community.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By Patrick L.
