Regenerating Tubules for Kidney Repair

2010
Stem/progenitor cells are in the focus of regenerative medicine for a future therapy of acute and chronic renal failure. However, broad knowledge about parenchymal regeneration in kidney is lacking. For that reason developmental pathways leading from stem/progenitor cells to newly formed tubules have to be investigated.

Secretion of tetraethylammonium by proximal tubules of rabbit kidneys

American Journal of Physiology-Renal Physiology, 1983
The secretory transport of tetraethylammonium (TEA) was investigated in perfused and nonperfused isolated S1, S2, and S3 segments of proximal tubules from rabbit kidneys. In the perfused tubules the transepithelial net secretory flux and in nonperfused tubules the TEA cellular uptake were saturable (Km = 67 microM, Vmax = 2,480 fmol X min-1 X mm-1 in ...

Primary Kidney Proximal Tubule Cells

2004
Primary rabbit kidney epithelial cell cultures can be obtained that express renal proximal tubule functions. Toward these ends, renal proximal tubules are purified from the rabbit kidney by the method of Brendel and Meezan. To summarize, each kidney is perfused with iron oxide, which becomes associated with glomeruli.

Phenylalanine hydroxylation in isolated rat kidney tubules

International Journal of Biochemistry, 1990
1. Phenylalanine hydroxylation has been demonstrated to occur in isolated rat kidney tubules under physiological conditions. 2. The hydroxylation flux response is hyperbolic with apparent Km and Vmax values of ca 85 microM phenylalanine and 49 nmol tyrosine formed/mg dry wt per hr respectively. 3.

[Tumorigenesis of kidney tubule].

Nihon rinsho. Japanese journal of clinical medicine, 1995
Renal cell carcinoma is derived from renal tubule, blastematous tubule or nephrogenic rest. Most common sporadic clear cell tumors have structural changes of the chromosomes, such as the cancer suppressor genes at 3p14, 3p21 or 3p25 (VHL gene). Cytogenetically, clear cell tumor (non papillary tumor) initially develops as a cancer, while papillary tumor

Role of Proximal Tubules in the Pathogenesis of Kidney Disease

2011
The proximal tubules make up a significant portion of the kidneys; proximal tubule epithelial cells are the most populous cell type in the kidney, and carry out diverse regulatory and endocrine functions where numerous transporters are located. Under normal circumstances, more than two thirds of filtered salt and water, and all filtered bicarbonate is ...

Hemoglobin absorption in the proximal tubules of the kidney in the rabbit

Journal of Ultrastructure Research, 1967
Relatively small quantities of hemoglobin, 1.5 mg per cubic centimeter of blood, were injected intravenously into rabbits, and ultrastructural changes in the proximal tubular epithelial cells of the kidney were followed over a 24-hour period. These experiments and prior experiments have shown that the hemoglobin is absorbed by proximal tubular cells of

Morphogenesis and histogenesis of the connecting tubule in the rat kidney

Anatomy and Embryology, 1982
At the start of its morphogenesis the tubule of an S-shaped body always attaches to the terminal ampulla of the collecting duct. It remains attached there for some time while the terminal ampulla sprouts toward the renal capsule. The most distal part of the tubule that rises to the ampulla forms the connecting tubule, morphogenically the oldest segment
