What is congenital diaphragmatic hernia?
Congenital diaphragmatic hernia is a birth defect where there is an abnormal opening in the diaphragm, allowing abdominal organs to move into the chest cavity, which can hinder lung development.
How does fetal tracheal occlusion work?
Fetal tracheal occlusion involves blocking the trachea to increase lung fluid and pressure, promoting lung growth in fetuses with congenital diaphragmatic hernia.
What are the advantages of using animal models?
Animal models allow researchers to study the disease in a controlled environment, assess treatment effects, and explore genetic factors.
Why is reversibility important in this technique?
Reversibility allows for the technique to be applied without permanent changes to the fetus, enabling further studies and reducing ethical concerns.
What diseases can this model help investigate?
This model can be used to study congenital diaphragmatic hernia and other lung diseases, such as pulmonary hypoplasia.
