Clinically, premenopausal patients suffer from higher recurrence rates, potentially implicating ovarian hormone 17B\u2010estradiol (E2) in disease pathogenesis. Despite its relationship with disease phenotype and severity, the mechanistic role of E2 in subglottic fibrosis has not been investigated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Primary human cell lines derived from the airway scar of iSGS patients were utilized for in\u00a0vitro study to assess the impact of E2 on proximal airway cells (fibroblasts, epithelial cells, and endothelial cells).

There was no significant difference in TEER measurements in airway epithelial cells grown at ALI following E2 exposure.
