heart valve development
Definition
Target type: biologicalprocess
The progression of a heart valve over time, from its formation to the mature structure. A heart valve is a structure that restricts the flow of blood to different regions of the heart and forms from an endocardial cushion. [GOC:mtg_heart]
Heart valve development is a complex and highly orchestrated process that involves multiple cell types and signaling pathways. It begins early in embryonic development and continues throughout fetal life.
**Early Development:**
* **Heart tube formation:** The heart starts as a simple tube that folds and forms four chambers.
* **Endocardial cushions:** At the point where the heart tube folds, specialized cells called endocardial cells proliferate and migrate, forming bulges called endocardial cushions. These cushions will become the foundation for the heart valves.
* **Atrioventricular canal:** This is the opening between the atria and ventricles, where the AV valves will eventually develop.
* **Outflow tract:** The connection between the ventricles and the aorta and pulmonary trunk, where the semilunar valves form.
**Valve Formation:**
* **Endocardial cushion remodeling:** Endocardial cushions undergo a series of transformations, including cell death, migration, and differentiation.
* **Valve leaflet formation:** The endocardial cushions eventually split into distinct leaflets, which will form the flaps of the valves.
* **Valve interstitial cells:** These cells populate the valve leaflets and produce the extracellular matrix, providing structural support.
* **Valve endothelium:** The surface of the valve leaflets is covered by a layer of endothelial cells, which help maintain valve function.
**Signal Pathways:**
* **Fibroblast growth factors (FGFs):** Important for endocardial cushion formation and valve leaflet development.
* **Bone morphogenetic proteins (BMPs):** Regulate valve leaflet growth and differentiation.
* **Wnt signaling:** Contributes to valve leaflet formation and patterning.
* **Notch signaling:** Plays a role in valve endothelial cell development.
**Later Stages:**
* **Valve maturation:** During fetal development, the valves continue to mature and refine their structure.
* **Valve function:** At birth, the valves become functional, ensuring unidirectional blood flow through the heart.
**Genetic Basis:**
* **Mutations in genes involved in valve development can lead to congenital heart defects, including valve abnormalities.**
* **Examples include mutations in genes encoding FGFs, BMPs, and other signaling molecules.**
**Overall, heart valve development is a finely-tuned process involving complex cellular interactions and signaling pathways. Understanding this process is crucial for diagnosing and treating congenital heart defects and for developing new therapeutic strategies for valvular heart disease.**'
