Menstrual stem cells in endometriosis

Study of the Role of Menstrual Blood-derived Stem Cells and the Immune Environment in Endometriosis

Observational University Rovira i Virgili · NCT07578480

This project will see if menstrual blood stem cells from women with endometriosis behave differently at the molecular and immune levels compared with cells from women without endometriosis.

What this trial studies

Researchers will collect menstrual blood from women aged 18–45, isolate menstrual blood-derived stem cells (MenSCs) and perform in vitro functional, molecular and immunological analyses. Findings in MenSCs will be validated against endometrial tissue and endometrioma samples when available. Results will be correlated with clinical features to identify patterns linked to disease severity and symptoms. The study is observational and does not involve experimental treatments.

Who should consider this trial

Good fit: Women aged 18–45 who can provide menstrual blood and either have a clinical/ecographic diagnosis of endometriosis or serve as controls without endometriosis, and who have not used hormonal, immunosuppressive, or antibiotic treatments in the prior 3 months are ideal candidates.

Not a fit: People under 18 or over 45, pregnant or breastfeeding women, those with active pelvic inflammatory or autoimmune disease, recent hormonal/immunosuppressive/antibiotic use, insufficient menstrual flow, active gynecological cancer, or positive HIV/HPV tests are unlikely to be eligible or to benefit from participation.

Why it matters

Potential benefit: If successful, this work could reveal cellular mechanisms that point to new biomarkers or therapeutic targets for endometriosis.

How similar studies have performed: A few smaller studies have characterized menstrual stem cells in gynecologic conditions, but broad molecular and immune profiling with direct tissue validation remains relatively novel.
