Quantitative analysis of the nephron during human fetal kidney development [PDF]
Vojnosanitetski Pregled, 2005 Background. The development of human kidney is a complex process. The number, shape, size, and distribution of nephrons as functional units in a kidney, provide some important information about the organization of the kidney. The aim of this study was to

Communications Biology, 2023 Kidney organoids have shown promise as evaluation tools, but their in vitro maturity remains limited. Transplantation into adult mice has aided in maturation; however, their lack of urinary tract connection limits long-term viability.

In vivo regeneration of neo-nephrons in rodents by renal progenitor cell transplantation
STAR Protocols, 2021 Summary: Renal progenitor cells induced from pluripotent stem cells have attracted attention as a cell source for organ regeneration. Here, we report an in vivo protocol for the regeneration of urine-producing nephrons, i.e., neo-nephrons, in mice.

Adaptive changes in GFR, tubular morphology, and transport in subtotal nephrectomized kidneys: modeling and analysis [PDF]
, 2017 Removal of renal mass stimulates anatomical and functional adaptations in the surviving nephrons, including elevations in single-nephron glomerular filtration rate (SNGFR) and tubular hypertrophy. A goal of this study is to assess the extent to which the

Direct physical contact between intercalated cells in the distal convoluted tubule and the afferent arteriole in mouse kidneys. [PDF]
PLoS ONE, 2013 Recent physiological studies in the kidney proposed the existence of a secondary feedback mechanism termed 'crosstalk' localized after the macula densa. This newly discovered crosstalk contact between the nephron tubule and its own afferent arteriole may

Afadin orients cell division to position the tubule lumen in developing renal tubules [PDF]
, 2017 In many types of tubules, continuity of the lumen is paramount to tubular function, yet how tubules generate lumen continuity in vivo is not known. We recently found the F-actin binding protein Afadin is required for lumen continuity in developing renal ...

Nephrology Dialysis Transplantation, 2002 One of the most remarkable transformations of cells during organogenesis is the epithelial transformation of nephrogenic mesenchyme to secretory nephrons. During recent years, gene targeting and organ culture approaches have been used efficiently to resolve key molecules involved in this multistage process.

Quantitative morphology of renal cortical structures during compensatory hypertrophy [PDF]
, 1998 The compensatory hypertrophy in different renal cortical structures was studied in rats 10 and 21 days after unilateral nephrectomy (UNX). Quantitative morphological/stereological analysis revealed significant increases in total renal cortical volume ...

Seminars in Interventional Radiology, 2014 Renal cell carcinoma (RCC) is a common malignancy with an increasing incidence.1 2 The classic triad of abdominal mass, hematuria, and flank pain accompanied by the various associated paraneoplastic syndromes (or the “internist's tumor”) are rare presentations of contemporary kidney cancer. With the current use and practice of modern abdominal imaging,
