MEN-ENDO: Menstrual Stem Cells in Endometriosis

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

Source: ClinicalTrials.gov · Last updated 11 May 2026

Brief summary (registry, in English)

Endometriosis is a chronic inflammatory condition characterized by the presence of endometrium-like tissue outside the uterine cavity. It is estimated to affect approximately 10% of women of reproductive age and it is associated with chronic pelvic pain and infertility, among other symptoms. Endometriosis involves complex changes in the body's cells and immune response. For this reason, the goal of this observational study is to characterize the functional, molecular, and immunological alterations in menstrual blood-derived stem cells (MenSCs) and differentiated decidual stromal cells in women with endometriosis; to validate these findings in endometrial tissue and endometriomas; and to establish their correlation with clinical parameters, with the aim of identifying key pathogenic mechanisms and potential therapeutic targets. The main questions it aims to answer are: * Are there functional and molecular changes in MenSCs from patients with endometriosis compared to healthy volunteers? * Are there any variations in the immune properties of MenSCs throughout the menstrual bleeding period in patients with endometriosis compared to healthy volunteers? * Are these changes also present in endometrial tissue and endometrioma samples? * Can these changes be correlated with clinical parameters in patients with endometriosis? * Can MenSCs serve as a potential therapeutic target for endometriosis? Some participants will be asked to provide menstrual blood on a single day, while others will provide samples during the first five days of menstruation. Additionally, all participants will answer questionnaires about their diet, physical activity, stress, and pain levels. Therefore, the study does not involve the evaluation of a specific intervention on the participants. The results will enable the identification of key altered mechanisms and potential therapeutic targets, thereby contributing to the development of more effective strategies for the diagnosis and treatment of the disease.
