Development of a Synthetic 3D Platform for Compartmentalized Kidney In Vitro Disease Modeling

Advanced Healthcare Materials, EarlyView.
A fully synthetic, compartmentalized 3D kidney disease model is introduced. The kidney model combines a PEG‐based hydrogel matrix with anisotropic, enzymatically degradable rod‐shaped microgels to spatially arrange a triple co‐culture of key renal epithelial, endothelial, and fibroblast cells.

In Vivo Clonal Analysis Reveals Lineage-Restricted Progenitor Characteristics in Mammalian Kidney Development, Maintenance, and Regeneration

Cell Reports, 2014
The mechanism and magnitude by which the mammalian kidney generates and maintains its proximal tubules, distal tubules, and collecting ducts remain controversial.

Knockdown of TMEM30A in renal tubular epithelial cells leads to reduced glucose absorption

BMC Nephrology, 2023
The kidney reabsorbs large amounts of glucose through Na+-glucose cotransporter 2 (SGLT2). P4-ATPase acts together with the β-subunit TMEM30A to mediate the asymmetric distribution of phosphatidylserine (PS), phosphatidylethanolamine (PE), and other ...

Continuous growth of proximal tubular kidney epithelial cells in hormone-supplemented serum-free medium. [PDF]

, 1982
An epithelial cell line from pig kidney (LLC-PK1) with properties of proximal tubular cells can be maintained indefinitely in hormone-supplemented serum-free medium. Continuous growth requires the presence of seven factors: transferrin, insulin, selenium,

An Intact Kidney Slice Model to Investigate Vasa Recta Properties and Function in situ [PDF]

, 2012
Background: Medullary blood flow is via vasa recta capillaries, which possess contractile pericytes. In vitro studies using isolated descending vasa recta show that pericytes can constrict/dilate descending vasa recta when vasoactive substances are ...

Highly Tunable and Cell‐Remodelable Thiol‐ene Alginate‐Peptide Crosslinked Hydrogels to Recreate Cellular and Organoid Microenvironments for Biofabrication

Advanced Healthcare Materials, EarlyView.
Norbornene‐functionalized alginate is crosslinked with a di‐thiolated peptide sequence cleavable by cell‐secreted matrix metalloproteinases and decorated with cell‐adhesion peptides upon exposure to UV. Thyroid follicles, endometrial and intestinal organoids are encapsulated in a gentle manner with high cell viability and correct phenotype ...

Protective effect of resveratrol on acrylamide-induced renal impairment

Folia Morphologica, 2021
BACKGROUND: Acrylamide (ACR) has a wide range of uses. It possesses a renal impairment effect. The work aimed to study the possible protecting role of resveratrol (RVS) over the ACR-mediated renal impairment in rats.

Visualization of Calcium Dynamics in Kidney Proximal Tubules [PDF]

Journal of the American Society of Nephrology, 2015
Intrarenal changes in cytoplasmic calcium levels have a key role in determining pathologic and pharmacologic responses in major kidney diseases. However, cell-specific delivery of calcium-sensitive probes in vivo remains problematic. We generated a transgenic rat stably expressing the green fluorescent protein-calmodulin-based genetically encoded ...

Proximal tubular deletion of superoxide dismutase-2 reveals disparate effects on kidney function in diabetes

Redox Biology
There is a large body of evidence implicating mitochondrial reactive oxygen species (ROS) overproduction and oxidative stress in the development of diabetic kidney disease and the deficiency of mitochondrial antioxidant systems in the kidney, such as ...
