Young blood for old kidneys? More questions than answers so far

Abstract:
The aging kidney has increased susceptibility to injury and decreased regenerative capacity. It is unknown if the effects of aging on acute kidney injury are reversible. In this issue, Liu et al., using a mouse heterochronic parabiosis ischemia-reperfusion model, demonstrate that a shared circulation between a young and older mouse results in decreased acute tubular injury. This study is an important first step using an interesting model, but many questions remain about how young blood reduces acute kidney injury in an older mouse.

Blood and Nerve Supply to the Kidney
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of...
Kidney Structure
External Anatomy of the Kidney
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
Internal Anatomy of the Kidney
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
