AHA Scientific Sessions 2026 Abstract
A signaling pathway controls heart-cell division in newborn mice
Newborn mice missing one pathway protein had hearts about 30% smaller than normal mice, with fewer heart muscle cells.Newborn mice missing one pathway protein had hearts about 30% smaller than normal mice, with fewer heart muscle cells.
Mouse studyPPAR signaling
Who was studiedOne-day-old mice lacking CD36, against normal mice
What changedHearts of newborn mice lacking CD36 were about 30% smaller than normal mice, with fewer heart muscle cells
The catchEntering the cell cycle does not mean cells completed division or replaced heart muscle
