* '''capillary loop''' - (C stage) The third stage in nephron development between 25-29 weeks. (stage sequence: V - S - C - M) | * '''capillary loop''' - (C stage) The third stage in nephron development between 25-29 weeks. (stage sequence: V - S - C - M) | ||
* '''Congenital Nephrotic Syndrome''' - (CNS) rare kidney disorder characterized by heavy proteinuria, hypoproteinemia, and edema starting soon after birth. Most cases are caused by genetic abnormalities in the components of the glomerular filtration barrier, especially nephrin and podocin. (More? {{renal abnormalities}}) | |||
* '''diabetes insipidus''' - The disorder is related to the hormone antidiuretic hormone (ADH, also called vasopressin) its synthesis, secretion, receptors and signaling pathway. In diabetes insipidus there is an excretion of large amounts (up to 30 litres/day) of a watery urine and an unremitting thirst. | * '''diabetes insipidus''' - The disorder is related to the hormone antidiuretic hormone (ADH, also called vasopressin) its synthesis, secretion, receptors and signaling pathway.

* '''neoplastic rest''' - In kidney development, a neoplastic rest can develop under either genetic or epigenetic influence from a hyperplastic rest, originating from an embryonic blastema cell. Normally the majority of nephrogenic rests either regress or become dormant. | * '''neoplastic rest''' - In kidney development, a neoplastic rest can develop under either genetic or epigenetic influence from a hyperplastic rest, originating from an embryonic blastema cell.

* '''nephrin''' - protein of the slit diaphragm of renal filtration barrier, located at the cell surface in the area between two podocytes. NPHS1 gene location {{Chr19}}q13.12, mutations in this gene are associated with Congenital Nephrotic Syndrome. (More? {{renal abnormalities}}) | |||
* '''nephrogenic rest''' - Used to describe the embryonic blastema cells which persist and under either genetic or epigenetic can change to become a neoplastic rest. These neoplastic rests can develop postnatally as a benign form (adenomatous rest) or a malignant Wilm's tumour form. The rests are further characterised by the time of generation leading to different anatomical kidney locations: early intralobar nephrogenic rests (within the renal lobe) and late pelilobar nephrogenic rests (periphery of the renal lobe) | * '''nephrogenic rest''' - Used to describe the embryonic blastema cells which persist and under either genetic or epigenetic can change to become a neoplastic rest.

* '''podocyte''' - (visceral epithelial cell) kidney glomerulus cell forming the main component of the glomerular filtration barrier. (glomerular podocyte) Kidney epithelial cell type in the nephron (kidney functional unit) located in the glomerulus. Podocytes form the visceral layer of Bowman's capsule and are at the filtration barrier between capillary blood and the nephron tubular system and function to ultrafiltrate blood, and support glomerular capillary pressures. The differentiation of podocytes involves the formation of cellular foot processes and then the slit membrane. (More?
