Cellular Antennas Reveal Heart Defect Secrets | Science News

Scientists have uncovered a hidden cellular communication system in tiny antenna-like structures called primary cilia, which may explain why some babies are born with heart defects. These cilia act as molecular signal hubs guiding stem cells to form heart muscle — and when key proteins within them malfunction due to genetic errors, heart development goes awry. Remarkably, this same system appears vital for building other organs like the brain, kidneys, and skeleton, offering a unifying theory for congenital heart disease linked to broader genetic syndromes. Researchers confirmed their findings by studying human genetic data and testing disruptions in zebrafish and stem cells — paving the way for better early detection and future treatments.
