A groundbreaking approach to diagnosing endometriosis offers potential to revolutionise research and treatment of the disease. Affecting one in ten women, endometriosis often goes undiagnosed for years. Traditionally, diagnosis involves invasive procedures like laparoscopy. However, scientists in Spain and France have developed a method of analysing blood-derived stem cells (MenSCs) directly from menstrual samples. This preserves the cells' molecular integrity, allowing researchers to study endometriosis more accurately. By using a technique common in cancer diagnosis, researchers achieved an 81% accuracy rate in distinguishing endometriosis patients from healthy individuals. This non-invasive method, developed by endogene.bio and collaborators, could reduce diagnosis time from years to weeks. The study has gained attention from the pharmaceutical industry, as potentially it could transform endometriosis management and patient care. The co-founder of endogene.bio says: ‘This world-first approach to endometriosis research and diagnosis is truly game-changing for women’s health.’
