Multimodal data analysis reveals asynchronous aging dynamics across female reproductive organs
摘要
Female reproductive aging has systemic health implications, yet tissue-level dynamics remain poorly understood. Here we integrate deep learning analysis of 1,112 histology images with RNA sequencing from 659 samples across seven female reproductive organs in donors aged 20–70 years. We uncover asynchronous trajectories: the ovary ages gradually, whereas the uterus shows an abrupt molecular and morphological shift around menopause. This uterine transition is independently supported by plasma proteomics data from a large population cohort, indicating that organ-linked aging signatures are detectable in circulation. Tissue segmentation highlights the myometrium as strongly age affected, with extracellular matrix remodeling and immune activation. Epithelial tissues also show coordinated age-related remodeling, with a sharp menopausal transition in the vaginal epithelium. Multi-omics factor analysis links these histological changes to nonlinear gene-expression shifts enriched for reproductive traits, including pelvic organ prolapse and age at menarche. Together, these findings establish menopause as a key inflection point in female aging and provide a tissue-resolved, multi-dataset framework for late-life health.
