Building primary epididymal cell models to look at CFTR gene regulation

Official title: Establishment of a Primary Epididymal Cell Model From Epididymal Samples to Study CFTR Gene Regulation

Run by University Hospital, Brest · NCT06045702 · Data updated 2026-11-12

This project will try to grow cells from epididymal tissue taken during planned surgery to see if they reveal how the CFTR gene is regulated in adult men with infertility, cystic fibrosis, or absence of the vas deferens.

Is this trial a fit for you?

Likely a good fit

Adult men (18+) who are scheduled for epididymal sampling surgery and can provide informed consent, including those with cystic fibrosis or bilateral absence of the vas deferens, are ideal candidates.

Probably not a fit

People who are not having epididymal harvesting surgery, minors, those under legal protection, or anyone seeking immediate clinical treatment rather than contributing tissue for research are unlikely to benefit directly.

What this trial studies

This observational project collects epididymal tissue samples during scheduled urologic surgery and establishes primary epididymal cell cultures. Researchers will map the 3D organization of chromatin at the CFTR locus and identify regulatory elements active in these cells. Participants include adult men undergoing epididymal sampling, including those with male infertility, cystic fibrosis, or congenital bilateral absence of the vas deferens. The goal is to connect CFTR regulatory architecture in epididymal cells to mechanisms underlying certain forms of male infertility.

Why it matters

Potential benefit: If successful, this work could improve understanding of how CFTR-related regulation contributes to male infertility and guide future diagnostic or therapeutic research.

How similar studies have gone: Related 3D chromatin and CFTR regulation studies have been done in other tissues, but using primary epididymal cells for this question is relatively novel and less well studied.
