Understanding how the heart becomes more efficient

点击翻译按钮获取中文摘要

The body demands that the heart function at utmost efficiency. Trabeculae – folds within the heart lumen – maximise blood flow, contribute to chamber development and form the electrical conduction network of the heart. Problems with trabeculae formation cause cardiomyopathy and arrhythmia and yet we do not understand its basic development. The project will investigate the earliest stages of when this tissue develops its identity and examine the signalling, genetic, cellular and extracellular cues required to instruct trabeculae to form in the heart. Findings from this research will revise our understanding of when and how trabeculae form and provide key information about how to grow and repair this important tissue.
