Biomedical researchers have found a new way to study endometrial diseases such as endometriosis and cancer. They were able to grow three-dimensional cell structures from diseased tissue of patients. The biobank can be used to unravel the disorders and test drugs.
Diseases of the endometrium are an important cause of infertility. One example is endometriosis, which is characterized by growth of endometrial-like tissue outside the uterine cavity, resulting in chronic abdominal pain and painful sexual intercourse. Up to half of the patients are subfertile or infertile. Treatment usually requires surgery and permanent hormonal therapy, which is incompatible with pregnancy.
Another important disorder is endometrial cancer, the most common gynecological cancer, with tumors growing in and from the endometrium. We need a better understanding of, and more effective treatments for both diseases. But in order to make progress, researchers have to be able to grow and study the endometrium in the lab.
Researchers at KU Leuven, a research university in Belgium, developed “organoids” from a healthy endometrium. These three-dimensional cell structures are grown in a petri dish from tissue fragments and cells of clinical biopsies. The organoids accurately replicate the original endometrial tissue from a broad spectrum of endometrial diseases, including endometriosis and endometrial cancer.
“The organoids form ‘avatars’, as it were, of the diseased tissue and can also be used to test the effect of drugs and new drug candidates,” senior author Hugo Vankelecom explained. “Our study shows that endometrial cancer organoids of different patients are each in a specific way sensitive to chemotherapeutic drugs. Further research will show whether such tests can be of help in the clinical treatment of individual patients. This is an example of what we call personalized medicine. Our new research model offers the potential to better understand and eventually treat uterine diseases such as endometriosis.”
