Strong evidence suggests that renal stem cells are located in the renal papilla. [2] Using stain-retaining assay (with bromodeoxyuridine, or BrdU), a low-cycling cell population was found in the papillary region, which was able to divide rapidly to repair the damage caused by transcient renal ischemia.

Intrinsic AKI refers to disease processes which directly damage the kidney itself. Intrinsic AKI can be due to one or more of the kidney's structures including the glomeruli, kidney tubules, or the interstitium. Common causes of each are glomerulonephritis, acute tubular necrosis (ATN), and acute interstitial nephritis (AIN), respectively.
In the mammalian kidney, the regeneration of the tubular component following an acute injury is well known. Recently regeneration of the glomerulus has also been documented. Following an acute injury, the proximal tubule is damaged more, and the injured epithelial cells slough off the basement membrane of the nephron.
When CKD occurs, the damaged kidneys "gradually lose their ability to filter waste, toxins, and extra water from the blood," explains Dr. Jason Nagata, a pediatrician at UCSF Benioff Children’s ...
Unlike chronic kidney disease, however, the kidneys can often recover from acute kidney injury, allowing the person with AKI to resume a normal life. People with acute kidney injury require supportive treatment until their kidneys recover function, and they often remain at increased risk of developing future kidney failure. [26]
Hemodialysis, also spelled haemodialysis, or simply dialysis, is a process of filtering the blood of a person whose kidneys are not working normally. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure.
