SOX17-positive rete testis epithelium is required for Sertoli valve formation and normal spermiogenesis in the male mouse
A valve-like structure called this Sertoli valve (SV) supports spermatogenesis by modulating the directional fluid flow in mouse testis. The SV formation is supported by its neighboring SOX17 + rete testis (RT). This study highlights the essential roles of RT and SV in spermatogenesis.

A zwitterionic near-infrared fluorophore for real-time ureter identification during laparoscopic abdominopelvic surgery
Iatrogenic injury of the ureters is a feared complication of laparoscopic abdominal surgery. Here the authors present the NIR fluorophore ZW800-1 as an intraoperative imaging agent for ureter mapping, showing its safety, pharmacokinetic properties, and efficacy in healthy volunteers and patients undergoing abdominopelvic surgery.

Symmetrical and asymmetrical division analysis provides evidence for a hierarchy of prostate epithelial cell lineages
The role of cell division modes of basal and luminal epithelial cells in prostate development and tumorigenesis is unclear. Here, the authors show that while luminal cells contribute to development and tumorigenesis via symmetrical divisions, basal cells do so through asymmetric divisions.
