Angiotensin II (AngII) is not essential for initial nephron and glomerular development in rat kidneys. However, AngII plays a crucial role in the normal growth and development of renal tubules and vasculature.
Area of Science:
- Nephrology
- Developmental Biology
- Physiology
Background:
- The renin-angiotensin system (RAS) is present in the fetal kidney early in development.
- Angiotensin II (AngII) is vital for normal fetal and neonatal renal function.
- Angiotensin II receptors mediate critical signals for growth and development.
Purpose of the Study:
- To review evidence on the essential role of AngII in kidney development.
- To investigate the impact of RAS blockade on renal development.
- To clarify AngII's specific contributions to nephrogenesis and organogenesis.
Main Methods:
- Review of existing experimental and clinical data.
- Analysis of studies involving Angiotensin converting enzyme (ACE) inhibition or AngII receptor blockade.
- Examination of findings from metanephric organ culture experiments.
Main Results:
- AngII receptor blockade or ACE inhibition leads to abnormalities in developing kidneys.
- Chronic RAS blockade in rats causes structural damage to tubules and blood vessels.
- Glomerular induction occurs even with AngII receptor blockade in organ culture.
Conclusions:
- Angiotensin II is not essential for nephron induction and glomerular development in rat kidneys.
- Angiotensin II is indispensable for the proper growth and development of renal tubules and vasculature.
- RAS blockade significantly impacts postnatal renal structure and function.

Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
