Establishment and Characterization of a Stromal Cell Line Derived From a Patient With Thoracic Endometriosis
Researchers established and characterized the TH-EM1 cell line from thoracic endometriosis implants, finding it expresses mesenchymal and embryonic markers, has chromosomal gains, and its growth is inhibited by medroxyprogesterone acetate.

The study established and characterized TH-EM1, a spontaneously growing stromal-like cell line derived from lung parenchymal endometriotic implants from a single patient with thoracic endometriosis. Cells grew long-term with a 5–6 day doubling time, and treatment with medroxyprogesterone acetate inhibited proliferation and induced morphological changes toward epithelial-like features; immunohistochemistry and flow cytometry showed expression of nuclear estrogen and progesterone receptors and erythropoietin receptor, along with CD9/CD13/CD73/CD90/CD105/CD157. The cells also expressed embryonic/pluripotency-associated markers SOX-2 and Nanog in a subset and fetal hemoglobin/α-globin in a substantial fraction, and cytogenetic analyses revealed normal metaphases with specific DNA copy-number gains. A major limitation is that the model is derived from one thoracic endometriosis patient and the characterization is largely phenotypic/genomic rather than functional across broader patient cohorts. This paper is centrally about endometriosis—specifically thoracic endometriosis—by creating an ex vivo stromal cell line from lung endometriotic implants.
