Sox17 mediates venous adaptive remodeling after arteriovenous fistula creation.

ABSTRACT:

Objective

Mature arteriovenous fistulae (AVF) are the gold standard vascular access allowing hemodialysis for patients with end-stage kidney disease. The rate of AVF failure remains high, reflecting an incomplete understanding of the biology of AVF maturation and failure. Sox17 is a transcription factor indispensable for the acquisition and maintenance of endothelial arterial identity. Because endothelial cells (EC) acquire dual arteriovenous identity after AVF creation, we determined whether Sox17 mediates venous remodeling in AVF.

Methods

Human preaccess vein, failed AVF, and mature AVF from second stage basilic vein transpositions were analyzed using immunofluorescence and single cell sequencing to determine Sox17 expression. Aortocaval AVF created in 9- to 11-week-old C5
