Description
Heart formation (GO:0060914) is the developmental process that generates the heart from unspecified parts, starting with specification of the heart field and arrival of cardiac neural crest cells, and concluding when the structural rudiment becomes recognizable. This process is fundamental to cardiovascular biology because defects in cardiogenesis underlie congenital heart defects and contribute to adult cardiac disease. Research into heart formation integrates developmental biology, metabolism and regenerative medicine, with evidence that metabolic flexibility and mitochondrial function are essential for normal cardiac development and repair [2,7,8]. Experimental models such as cardiac organoids and genetic knockouts have revealed that perturbations in metabolic and signaling pathways disrupt heart formation and lead to cardiomyopathy [3,4]. Key molecular players include RNA-binding proteins, metabolic enzymes and mitochondrial complex components that modulate cardiac stress responses and regeneration [1,5,6]. Understanding the mechanisms of heart formation is therefore critical for identifying therapeutic targets for heart failure and for advancing cardiac regenerative medicine [5,6,8].

What Is GO:0060914?
GO:0060914 heart formation is defined as the developmental process pertaining to the initial formation of the heart from unspecified parts. It begins with the specific processes that contribute to the appearance of the heart field and the arrival of cardiac neural crest to the heart region, and it ends when the structural rudiment is recognizable. The synonym cardiogenesis captures the same concept.
Why Is heart formation Important in Cell Biology?
Heart formation is essential because it establishes the structural and functional foundation of the cardiovascular system. Defects in this process cause congenital heart disease and predispose to later cardiac dysfunction. Moreover, pathways active during heart formation are reawakened in cardiac repair and regeneration, making this process a rich source of therapeutic targets for myocardial infarction and heart failure [5,6,8]. Metabolic and mitochondrial regulators identified in heart formation studies, such as AMPKα2 and COX7A1, directly influence cardiomyopathy and regeneration, underscoring the translational importance of this GO term [4,5].
• Heart formation is the developmental origin of all cardiac structures and function.
• Disruption of heart formation causes congenital heart defects and embryonic lethality.
• Metabolic flexibility and mitochondrial function are required for normal heart formation and repair [2,7,8].
• RNA-binding proteins such as RBMS1 modulate cardiac fibrosis and heart failure, linking heart formation pathways to adult disease.
• AMPKα2 inhibition under hyperglycemia promotes diabetic cardiomyopathy, showing metabolic control of cardiac development and homeostasis.

What Happens During heart formation?
Heart field specification and cardiac neural crest arrival
In simple terms: The heart starts as a group of unspecified cells that are told to become heart tissue, and neural crest cells migrate to the heart region.
Heart formation begins with the appearance of the heart field, a population of unspecified progenitors that acquire cardiac identity. This step involves signaling that specifies cardiac mesoderm and the arrival of cardiac neural crest cells to the heart region. Disruption of these early events impairs subsequent morphogenesis. Metabolic and mitochondrial function are already important at this stage, as cardiac progenitors require energy for proliferation and differentiation [2,7,8].
Formation of the cardiac tube and looping
In simple terms: The early heart cells organize into a tube that then bends and loops to shape the future chambers.
After specification, cardiac progenitors organize into a linear heart tube that undergoes looping, a critical morphogenetic step. This process depends on coordinated cell movements and differentiation. Mitochondrial complex IV dimerization, regulated by COX7A1, supports cardiac physiology and regeneration, indicating that mitochondrial function is required for proper heart tube development and later repair. Metabolic flexibility, including fatty acid metabolism, is also essential for cardiac health and disease.
Chamber specification and septation
In simple terms: The heart tube develops distinct chambers and divides into separate left and right sides.
Chamber specification and septation establish the four-chambered heart. These steps require precise transcriptional and signaling control. Perturbations in metabolic pathways, such as AMPKα2 inhibition under hyperglycemia, induce diabetic cardiomyopathy by promoting mitochondria-associated endoplasmic reticulum membranes, linking metabolic stress to structural and functional cardiac defects. RNA-binding proteins like RBMS1 also influence myocardial fibrosis and heart failure, suggesting post-transcriptional regulation is important in cardiac remodeling.
Cardiac maturation and metabolic switch
In simple terms: The heart matures and switches to using fat for energy, which is needed for its continuous pumping.
During maturation, the heart undergoes a metabolic switch from glycolysis to fatty acid oxidation to meet high energy demands. Cardiac basal metabolism is a key determinant of cardiac performance. Mitochondrial dysfunction contributes to cardiomyopathy and heart failure, highlighting the importance of metabolic maturation in heart formation and maintenance. PSAT1 promotes serine synthesis and cardiac repair after myocardial infarction, indicating that amino acid metabolism supports cardiac regeneration.
Cardiac neural crest contribution to outflow tract and septation
In simple terms: Neural crest cells help build the outflow tract and divide the heart's major vessels.
Cardiac neural crest cells migrate to the heart and contribute to the outflow tract and septation. Their arrival is a defining feature of heart formation per the GO definition. Defects in neural crest contribution lead to conotruncal heart defects. Although specific neural crest genes are not detailed in the provided citations, the process is integral to heart formation and is influenced by metabolic and mitochondrial status [2,5,8].

How Is heart formation Regulated?
Heart formation is regulated by metabolic and signaling pathways that sense energy status and stress. AMPKα2 acts as a key energy sensor; its inhibition under hyperglycemia promotes mitochondria-associated endoplasmic reticulum membranes and diabetic cardiomyopathy. Mitochondrial complex IV dimerization, controlled by COX7A1, regulates cardiac regeneration and skeletal muscle physiology. RNA-binding protein RBMS1 modulates myocardial fibrosis and heart failure, indicating post-transcriptional control. Metabolic flexibility, including fatty acid oxidation, is essential for cardiac health, and its dysregulation contributes to heart failure and cardiometabolic diseases. Mitochondrial dysfunction is a central mechanism in cardiomyopathy and heart failure, linking energetic collapse to therapeutic opportunities. Cardiac basal metabolism sets the energetic foundation for cardiac function. PSAT1-dependent serine synthesis supports cardiac repair after myocardial infarction, revealing amino acid metabolic regulation.

Heart failure and myocardial fibrosis
Heart failure is a major consequence of disrupted cardiac development and homeostasis. RBMS1 deficiency improves myocardial fibrosis and heart failure, suggesting that RBMS1 is a potential therapeutic target. Metabolic inflexibility and mitochondrial dysfunction contribute to heart failure progression [2,8]. AMPKα2 inhibition under hyperglycemia induces diabetic cardiomyopathy, a precursor to heart failure.
Diabetic cardiomyopathy and metabolic cardiomyopathy
Hyperglycemia-driven inhibition of AMPKα2 promotes mitochondria-associated endoplasmic reticulum membranes and diabetic cardiomyopathy in vivo. Metabolic flexibility, particularly fatty acid metabolism, is critical in cardiometabolic diseases, and its impairment leads to cardiac dysfunction. Mitochondrial dysfunction is a hallmark of cardiomyopathy and heart failure, offering therapeutic opportunities.
Myocardial infarction and cardiac regeneration
COX7A1 controls heart regeneration through complex IV dimerization, linking mitochondrial function to regenerative capacity. PSAT1 promotes serine synthesis and cardiac repair after myocardial infarction, highlighting metabolic reprogramming as a therapeutic strategy. Cardiac basal metabolism influences the heart's ability to recover from injury.
Cardiotoxicity and environmental stress
Polystyrene nanoplastic-induced cardiotoxicity has been studied using cardiac organoid-on-a-chip, revealing dynamic insights into heart formation and injury responses. Such models are valuable for assessing environmental and pharmacological cardiotoxicity.
