    Local estrogen is used to improve vaginal mucosal status in postmenopausal women with pelvic organ prolapse, but clinical outcomes are inconsistent.

  • 2

    The study utilized single-cell RNA sequencing and spatial transcriptomics to analyze postmenopausal vaginal wall tissues.

  • 3

    Estrogen promotes the expansion and spatial redistribution of HAS1+ fibroblasts, forming a structured perivascular niche.

  • 4

    This spatial co-localization enhances fibroblast-pericyte interactions and activates pro-repair signaling cascades.

  • 5

    The findings suggest that estrogen organizes multicellular reparative niches rather than causing non-selective tissue activation.
