Abstract

Endometriosis, the growth of endometrial tissue outside the uterine cavity, is a common gynecological disorder affecting 10% to 15% of women in their reproductive years. Retrograde menstrual shedding containing endometrial stem/progenitor cells has been postulated to be involved in its pathogenesis. In this study, we identified putative endometriotic stem/progenitor cells by their colony-forming potential, self-renewal capacity, and multipotency. Purified epithelial and stromal cells isolated from ovarian endometriotic cysts formed large and small colony-forming units (CFUs) in clonogenic assay. The colony-forming activity of epithelial and stromal cells was found to differ greatly between autologous endometrium and ovarian endometrioma samples. The large CFUs could propagate more than the small CFUs. The endometriotic epithelial small CFUs expressed epithelial markers (epithelial cell adhesion molecule, cytokeratin, and α6 integrin); only occasional large CFUs expressed α6 integrin. Aside from the expression of fibroblast markers, stromal CFUs also expressed three somatic stem cell markers: sal-like 4, CD133, and Musashi-1. Endometriotic stromal cells derived from large CFUs could differentiate into four mesenchymal lineages when cultured in the respective inducing-media, as determined by histochemical staining and RT-PCR of lineage specific markers. These findings demonstrate that ovarian endometrioma contains a subset of cells displaying somatic stem cell properties.

  • MSCs and epithelial progenitor cells isolated from ovarian endometriomas do not show increased clonogenicity or self-renewal compared to endometrial stem cells.

    “Remarkably, MSCs and epithelial progenitor cells isolated from ovarian endometriomas do not show increased clonogenicity or self-renewal compared to endometrial stem cells, which might have explained the increased survival capacity in endometriosis (Chan et al., 2011;Li et al., 2014).”

    From Endometriosis and nuclear receptors (2019) · cites this paper as Chan et al., 2011

    The Clonogenicity section reports significantly lower colony-forming efficiency for both epithelial and stromal cells from ovarian endometriomas than from normal endometrium. The Serial Cloning section measures self-renewal within endometrioma-derived colonies, comparing large with small colonies, but does not compare their self-renewal with endometrial stem cells. The proposed link to increased survival capacity is not established by these passages. (LLM, conf=0.87)

  • Endometriotic lesions harbor multipotent, colony-forming MSCs.

    “Similar to endometrium, endometriotic lesions also harbor multipotent, colony-forming MSCs (Chan et al., 2011).”

    From Endometriosis and nuclear receptors (2019) · cites this paper as Chan et al., 2011

    The Abstract reports colony-forming cells isolated from ovarian endometriotic cysts, and the Cellular Phenotypes and Multipotency section reports that stromal large CFUs differentiated into four mesenchymal lineages. The study describes these as putative stem/progenitor cells and examines ovarian endometriomas, so it does not establish the claim for endometriotic lesions generally or definitively identify the cells as MSCs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
