To establish and characterize long-term, self-renewing 3D human endometrial epithelial organoids for modeling uterine gland biology and hormonal responsiveness.
Derived 3D endometrial epithelial organoids (EEO) from human endometrial biopsies obtained from two donors.
Treated derived organoids with estrogen for 2 days or estrogen plus medroxyprogesterone acetate for 6 days.
Characterized growth, genetic stability, and hormone-driven changes using FOXA2 staining, RT-qPCR, bulk RNA-sequencing, and single-cell RNA-sequencing.
Derived EEO expanded long-term, retained genetic stability, tolerated cryopreservation, expressed the glandular marker FOXA2, and demonstrated appropriate steroid hormone receptor regulation.
Transcriptomic analyses revealed hormone-dependent shifts in epithelial cell subtype proportions and gene expression profiles that replicated natural proliferative and secretory phase endometrium.
