Researchers have created the most detailed human Heart Cell Atlas to date, providing new insights into cardiac health and disease. The study, published in Nature, maps the specialized tissue of the cardiac conduction system, which is responsible for initiating heartbeats. The atlas, part of the international Human Cell Atlas initiative, describes 75 different cell states and reveals how these cells communicate with each other. The findings will aid in understanding heart rhythm disorders and developing targeted therapies. The study also introduces a computational tool called Drug2cell, which predicts drug targets and side effects, offering valuable information for evaluating new treatments.
