Getting to the heart of the matter: The winning entries of heart imagery competition 'Reflections of Research' revealed
'Caught in the net': This is the front view of a developing two day old zebrafish heart. The green cells are heart muscle cells, and the red and blue staining shows components that make up the muscle. The early heart tube has started to loop. It consists of two sections – the large, thin atrium (where blood flows in) and the smaller, thicker ventricle (where blood leaves the heart).
