Key result
Disrupting FGF/FRS2α signaling drives premature cardiac progenitor differentiation by increasing autophagy.
Why the study?
The molecular mechanism by which FGF signaling regulates cardiogenesis and cardiac progenitor cell differentiation is not fully understood.
Population
Mice with tissue-specific ablation of FGF receptors and Frs2α in heart progenitor cells and embryoid body cultures of mouse embryonic stem cells
Comparison
Disruption of FGF signaling vs intact FGF signaling
Design
Preclinical study using genetically modified mice and embryoid body cultures

Autophagy timing in cardiac progenitors may shape heart development; hypothesis-generating for congenital defects and regeneration strategies.
FGF/FRS2α-mediated signals prevent premature differentiation of heart progenitor cells by suppressing autophagy, providing the first evidence of autophagy's role in heart progenitor differentiation.
Zhang et al. (2011) studied Heart development and cardiogenesis. Tissue-specific ablation of FGF receptors and Frs2α was evaluated on Cardiac progenitor cell differentiation and autophagy activity. Disruption of FGF/FRS2α-mediated signals leads to premature differentiation of cardiac progenitor cells by increasing autophagy activity.
