High-resolution mapping of endometriosis

A recent study has enabled the high-resolution mapping of endometriosis lesions, revealing potential cellular interactions responsible for pain. This scientific advancement offers new insights into the mechanisms of the disease. On a medical image, a lesion may appear small. In the body, however, it may be situated in an environment much more active than it seems. This discrepancy is being clarified by a study published on October 9, 2026, in Nature Communications: researchers have mapped endometriosis lesions at very high resolution to understand which cells are present, particularly in cases of proximity to glands and nerve structures.

Potential mechanism for pain

The result does not change the current management of patients. Rather, it provides a potential mechanism: in some lesions, nerve cells related to pain appear close to immune cells and support cells, a proximity that could contribute to inflammation and painful signals.

Understanding endometriosis

Endometriosis is characterized by the presence of tissue resembling the endometrium outside the uterus. Its pains remain difficult to explain by a single mechanism, because the disease does not simply reduce to the presence of a visible lesion.

Patient and researcher perspective

"Doctors tend to minimize the symptoms, stating that menstrual pain is normally painful and that other women feel the same thing," explains Caroline Haney, a developmental biologist at the University of Jacksonville (JAX) and an endometriosis patient who led the research. "However, it turns out that the reality is very different. The pain is not just psychological; it is a biological reaction, a true pain signal coming from the body's neurons."
