Examining how individual heart cells develop is revealing how the cells make decisions to form a working heart.

Once an adult heart is damaged, it has no ability to heal itself. Dr Nathan Palpant at the Institute for Molecular Bioscience at the University of Queensland and Associate Professor Joseph Powell at the Garvan Institute of Medical Research and the University of New South Wales are trying to understand how that might be changed by tracking individual stem cells along their journey to becoming heart cells.

“Heart development is a difficult and complicated process, but we think the answers to heart repair are likely to lie in understanding heart development,” Nathan says. “So we are using stem cells to model development as it occurs in our bodies.” Continue reading Studying heart development one cell at a time →
