GSE130664 Primate Ovarian Aging

Single-cell transcriptomic atlas of the ageing cynomolgus macaque ovary (Wang et al., Cell 2020). Analysis here covers QC, clustering, UMAP, cell-type annotation and an old (OF) vs young (YF) comparison on the GSE130664_primate_ovarian_aging_counts.h5ad matrix (4 aged + 4 young females; ovarian compartments OCB / OCS / OM / OO).

Old vs Young composition

Composition shift across ovarian ageing (OF aged vs YF young). Theca and oocyte fractions fall with age; stroma, smooth muscle and granulosa differ as ovarian architecture remodels.

Differential expression — Old vs Young

Wilcoxon rank-sums (all cells); top 50 up/down by adjusted p-value. Antioxidant / stress responses and reproductive markers are key ageing signals.

Antioxidant / stress markers (Oocyte · Granulosa · Stroma)

Consistent with the paper: antioxidant capacity declines with age — e.g. GSR (glutathione reductase) is lower in aged oocytes and stroma.
