Summary
Kidney size is determined during development, but adult kidneys can grow. This review explores kidney growth mechanisms from development through adulthood, aiding stem cell therapies.
Area of Science:
- Nephrology
- Developmental Biology
- Physiology
Background:
- Kidney functional mass is crucial for adult health.
- Nephron endowment is established during development, with no known nephrogenesis post-development.
- Adult kidneys retain growth potential, demonstrated by compensatory hypertrophy after contralateral kidney loss.
Purpose of the Study:
- To review mechanisms controlling kidney size regulation.
- To examine nephron formation and cessation of nephrogenesis.
- To explore growth hormone-insulin-like growth factor signaling in kidney growth.
- To compare juvenile kidney growth with adult compensatory growth.
Main Methods:
- Review of existing literature on kidney development and growth.
- Analysis of genetic, cell biological, and hormonal controls.
- Examination of mouse models for kidney growth studies.
- Comparison of developmental, juvenile, and adult compensatory kidney growth.
Main Results:
- Nephrogenesis ceases post-development, fixing nephron number.
- Growth hormone and insulin-like growth factor pathways influence kidney growth pre- and postnatally.
- Compensatory kidney growth in adults shares mechanisms with juvenile growth.
Conclusions:
- Understanding kidney size regulation is key to addressing kidney disease.
- Mechanisms of kidney growth inform stem cell-based tissue generation.
- Further research into kidney growth set-points can advance regenerative medicine.

Kidney Structure
70.7K
The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

Nephrons
3.6K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

Physiology of the Genitourinary System I: Renal Blood Flow and Glomerular Filtration
114
The kidneys are vital organs responsible for regulating blood filtration, waste excretion, and fluid balance, all of which are crucial for maintaining homeostasis. Renal physiology examines renal blood flow, glomerular filtration, and urine formation, ensuring the body’s internal environment remains stable.Renal Blood FlowThe kidneys receive about 20-25% of the cardiac output, typically around 1200 mL of blood per minute in an average adult. Blood flows into the kidneys through the renal...

Introduction to Urinary System
4.4K
The urinary system consists of two kidneys, two ureters, the urinary bladder, and the urethra.
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...

Glomerular Filtration Rate and its Regulation
3.5K
The Glomerular Filtration Rate (GFR) is a measure of kidney function, reflecting the volume of filtrate formed per minute in the kidneys. On average, GFR is approximately 125 mL/min in males and 105 mL/min in females. Maintaining a relatively constant GFR is essential for the kidneys to effectively regulate body fluid homeostasis and maintain extracellular stability.
GFR regulation involves two primary intrinsic controls: the myogenic and tubuloglomerular feedback mechanisms.

Physiology of the Genitourinary System II: Tubular Reabsorption and Secretion
120
The kidneys maintain homeostasis through filtration, reabsorption, and secretion. Tubular reabsorption and secretion are crucial in forming urine and regulating electrolytes, water balance, and waste elimination.Tubular Reabsorption and Secretion ProcessesTubular reabsorption is the process that reclaims essential substances such as electrolytes, glucose, amino acids, and water from the glomerular filtrate back into the bloodstream. This is achieved through passive and active transport...
