These microscopy images demonstrate the effects of Notch signalling on the hearts of newborn mice (top) and of adult mice after a heart attack (bottom). In a normal neonatal heart (top left), the two major heart chambers (ventricles) are clearly separated by tissue (septum). But when Notch signalling was inactivated in an embryo’s heart muscle cells, the septum between the ventricles of the newborn mouse’s heart was incomplete (asterisk). The same defect commonly occurs in humans with congenital heart disease, often leading to circulatory distress. In the images of adult hearts (bottom), healthy tissue is shown in red and damaged tissue in blue. Normally (bottom left), a heart attack causes extensive tissue damage to the left ventricle (right-hand cavity), but mice in which Notch was re-activated after the heart attack had reduced tissue damage (bottom right) and improved cardiac function.

From fruit fly wings to heart failure. Why Not(ch)?

21 September 2009 This microscopy image, taken ten days after injury, shows that the muscle fibres of normal mice (left) had re-grown, while in mice which couldn’t boost C/EBPβ production (right) there were still many fibres that had not regenerated (arrowheads), and the tissue had a number of scars (arrows).
