Objective:
To study immunophenotype, differential proliferation capacity, invasiveness, adhesion, and cytokine production in ectopic and eutopic endometrial stromal cells (EESCs and EuESCs) from patients with endometriosis.
Design:
In vitro study.
Setting:
Academic research center.
Patient(S):
Patients with ovarian endometriosis (endometrioma) and nonendometriotic controls.
Intervention(S):
None.
Main Outcome Measure(S):
EESCs and EuESCs from 25 patients with endometrioma and ESCs from 20 nonendometriotic controls (CESCs) were isolated, and their immunophenotype, proliferation, invasion, adhesion, and cytokine production were assessed and compared.
Result(S):
Isolated ESCs from all three sources expressed markers specific for cells of mesenchymal origin but were negative for hematopoietic markers. EESCs exhibited a significantly lower proliferation rate in fibronectin-coated plates and less invasive capacity compared with CESCs or EuESCs. Among all stromal cell groups studied, EuESCs showed the highest invasive behavior. EESCs adhered more firmly to extracellular matrix than EuESCs or CESCs in all time intervals examined. The levels of interleukin (IL) -6 and IL-8 production by EESCs were significantly higher compared with those of EuESCs or CESCs.
Conclusion(S):
The results of the present study demonstrated that retrograde menstruation alone does not account for the pathogenesis of endometriosis as eutopic and ectopic counterparts of ESCs from patients with endometriosis exhibit differential invasive, adhesive, and proliferative behavior.

Proliferative Phase
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
